Located in wuxi city, ChongAnOu in wuxi city is the political, economic and cultural center, the area 17.82 square kilometers and a population of 18.47, wide, chung Ann temple, tongjiang, wide red horse pier, jianghai road, six streets, eight village, 34 community. 2004 GDP 118.01 billion yuan, the total retail sales of consumer 109.47 billion yuan, fixed assets investment 32.08 billion yuan, the total import and export trade, the general budget of $4,495 usd income chinas piracy rateoverthree billion yuan, on-the-job worker average wage 21339 yuan.
ChongAnOu with mining mineral resources is mainly the value of clay, limestone, marble, etc nonmetalliferous ore.
The limestone is a source of sedimentary rock formation, the main components are calcium carbonate, calcium and magnesium carbonate or carbonate and magnesium carbonate mixture. Heavy crystallization limestone, strong microcrystalline limestone and can HuaDou lime as the polishing marble of publicity and limestone or sales, particularly in the United States. According to the different density range, forming the limestone is divided into three subclasses:
The limestone is the natural features of many distinct characteristics, such as: calcite lines or spots, fossil or shell structure, hole, slender, open beehive structure and texture, iron, similar to the structure and lime crystals. One or more of these features of the combination of the texture. Limestone,
Marble marble is name of commodity, not petrological definition. Marble is a natural architectural decoration material, generally refers to decorate a function, can be processed with ChengJianZhu stone or handicrafts have bad or deterioration of carbonate. It is China’s yunnan (some features of the flowery colour and pattern with the stone. Marble tuyuhun marble, limestone, dolomite, and by different carbonate formation altered the skarn and marble, etc.
Marble is mainly used in processing various shape, plank, building of metope, ground, Taiwan, columns, and also used in building such as tablet, towers commemorative statue, etc. Marble can also carved arts &crafts, stationery, lamps and lanterns, such practical artwork.
Not long ago, use the natural ShiCai as architectural decoration materials or very extravagant, however, because stone mining and processing technology development, the natural stone material has been large scope. And the clothing industry, stone industry will have fashion trend. Not long ago, red and yellow stone in great demand, but soon, use black stone become people after the tide. Black stone, give a person a kind of decorous, high-grade impression, through the mirror finishing after give a person a kind of dignified showily feel, inside.
But not all black stone can be used. Even today, there are still many outsiders to all of the high hardness, low hardness of granite stone called as marble. This not only errors and very dangerous, especially when a natural stone material, due to an error or misleading name, with its mechanical properties, a typical example is “Belgium granite” (Belgium granite is a kind of limestone and Sweden, dark granite “. They are by no means hard stone, because they are a kind of limestone, while another basaltic).
In addition, in the past few years stone industry formed a kind of common but not fitting habits: because reluctant to let people know mop wipe the origin, people no longer according to the origin or stone material to the breed. Stone, Such as “red”, and not Santiago, Chile, but from Ukraine “Dallas pink” from Brazil instead of Dallas, etc. On the other hand, the existing natural stone material is the name of the commodity name by these so-called replaced. As India’s called “super” rock has ten different brand name. Some companies will no longer use the name of natural stone figures, but most of the designated a stone processing companies and users to confuse.
1 black rock types
Rock can be roughly divided into hard rock and soft rock. Hard rock, including granite and black granite and hui diabase. Soft rock including sedimentary limestone and clay, such as schist and metamorphic albitite, such as marble.
Granite is the most common on this planet a rock. It is a kind of mineral elements and science according to the definition of hard stone material carefully. But this is not all kinds of hard stone universally applicable definition. Most commonly, for the light of granite texture is fine, it’s hard stone texture structure does not follow any special rules. Example: it can be both spots, also have stripes, and may have throughout the petrologic interruption, such as pulse stones and texture of plagioclase texture. Black granite in the earth couldn’t find anywhere else. Most were mistakenly called granite black stone is either a fai, such as India’s long rock “baby” (” baby “is a kind of xinhui long since India) and” black rock, “either panama rock in a flash of long as” black “in Brazil in Brazil. These granite “relatives” and granite has not the same chemical composition. Once, can be defined as granite. ),
The transfer mode, wulian counties as a major task of economic work and working direction, actively adjust the industrial structure optimization, stone material industrial transformation and upgrading of mineral resources and the sustainable development.
Tianyu stone company in wulian counties, technical personnel are busy commissioning new stone machine, polished in the workshop, another set of equipment is full already debugging good work. The same granite, production cost of raw materials, new and old equipment production of every square metre is sent the price of plank 20 yuan.
Tianyu stone company manager ChengLiuJiang: as the enterprise, to realize the transition, and upgrade the way is to update production equipment and production technology, this product can have the technology content, to win the market.
Currently has more than a thousand home wulian counties of stone and mining enterprises, has completed scale expansion stages of development, from small tasks, clean, upgrade to upgrade, the depth of the new period of transition excessive.
Boss: before mine by using explosive stones, neither security also waste a great deal of stone, now the wheel curium cut like the cut tofu, don’t waste not, the production efficiency is greatly improved, safety and security.
Stone industry is wulian counties “11th five-year plan”, cultivate the pillar industries, only the stone industry street town in 2009 will achieve output of 30 million yuan. For advancing the stone industry structure adjustment, wulian counties to put forward new technology, new technology, new equipment, new products, processing, actively develop special stone, stone, stone industry function to many varieties, high quality, high efficiency.
Wulian counties street town mayor GuanRenTao: transfer mode, structure, for our industry is changed stone mining, past the vulgar, low level processing technology, efficient and environmentally friendly development path, promote the stone industry concentration, intensive, industrial cluster development.
Hubei stone material industrial association, said, “LiuXiaoWen secretary-general of Chinese building materials industry stone industry as an integral part of the basic construction in our country play a positive role in hubei stone industry. After ten years of low after nearly three years, wandering, its sales from the eighth national already up to the fifth, and resource potential, the development of hubei power, stone industry is rising.” .
LiuXiaoWen firstly introduces to the reporter a stone resources distribution in hubei province. He said China township — marble TongShan county in the $1 billion in marble of mineral resources, with a HuangGangShi by comparing shandong granite billions of dollars in value of mineral resources. Yichang predict, shiyan of granite, yun county whole area of sandstone, SLATE and shale also abundant mineral resources, etc.
LiuXiaoWen says, two years ago, HuangGangShi on granite mining still belongs to a small mill, the annual output of not more than five million square meters, large mining cannot exploitation. Since the city through investment has attracted many fujian, zhejiang, stone, increased after investors, scientific mines exploitation of small mill is away from here.
On market development, LiuXiaoWen tells a reporter, in recent years has attracted MaChengShi huanggang 25 when scale stone caves with industrial production enterprises. Employees nearly 49 people. In 2007, the stone material enterprise in realizing industrial output 5.12 million yuan. Production basis of the white stone series product sales throughout the country and Europe and the United States. Last year, only one area of stone huanggang reached 1,300 million square meters of production, the mother-town of 5%, and the expected by the end of this year, the output will reach 17 million square meters. MaChengShi last year about 900 million square meters of production of granite, the yield of granite 2/3, is expected to yield can reach this year, 13 million square metre.
LiuXiao said, the hubei stone market sales in the local investment primarily established tradition of fujian investors, and the marketing network of manufacturing enterprises to digest. QiChunXian an investment company last year, more than 70 million square meters of production for himself all the granite investment this year, the company will be used to 160 million square meters, expansion and have continued to expand production plan.
In hubei stone material industrial market prospects, LiuXiao said, as local municipal construction, and speed up the pace of stone industry itself, technology innovation and the constant expansion of hubei province, is a promising market prospect of stone. Hubei stone industry in the traditional product to make, on the basis of field development to processing.
For example, LiuXiaoWen HuangGangShi TuanFeng county but store the tombstone material production ShiHuang town in 20 years ago, the product exports Japan, but the town’s economic demand has not developed. Investigate its reason, is because of the town without processing stone products to sell directly, xin economic benefit is very low. Now, but the shop has its own processing enterprise, a tombstone price can sell to hundreds of thousands of yuan, or $. Therefore, the development of stone enterprises must pay processing this field. At present, the market demand of the tombstone, market supply is insufficient. Appreciation, if the space of mining waste materials or pull into stone processing and shale, tombstone products. It is very wide prospect.
LiuXiaoWen stressed, stone market, we should pay attention to domestic market development, pay attention to the international market development, because the SLATE, shale market mainly in abroad. With the implementation of the strategy in the rise of the central region. Hubei stone industry developed coastal areas, if undertake seize the opportunity, industrial transfer in recent years will have a leap-forward development.

Marble is relatively softer stone, the hardness of the table (MOHS), marble is about level 3 (up to 10). Like marble and teeth formation by the calcium. If something is too hard to bite, the teeth will be broken, eating too much sugar, the teeth will be perforated. Stone is also true. If the stone surface of the reagents used properly, Stone began to decay and form cavities.
Here is the famous Mohs hardness (MOHS).This standard is developed in the nineteenth century, it helps to identify the strength and hardness of stone used in order to apply to take the appropriate measures. For example, the hardness of the lower stone need softer reagent, Tuoxi times more often.
Mohs hardness
1. Talcum
2. Gypsum
3. Calcite (mostly marble)
4. Fluorite
5. Apatite
6. Feldspar (granite)
7.7. Quartz (granite)
8. Topaz
9. Corundum
10. Diamond
Mohs hardness is used to measure the degree of stone wear. When the sediment or sand than the hard stone surface, it will scratch the stone. Such as hard plastic hardness rating of about 2.0, it will not scratch the grade 3 calcite (marble). Hardness is 6 grains of sand will scratch the 3 level but will not scratch the seven calcite quartz stone that is granite. Hardness level, the more wear. Sediment building outside the hardness value was 3.0 to 7.0
America’s global financial crisis and gradually influence and spread worldwide each big industry, China also inevitable, and has gradually spread to the entity economy and diffusion. At the same time, as the end of the real estate sector stone industry in the global economy, a recession situation, did not really touched bottom stone, more not synchronous picked up year-on-year growth of signs, but overall, annulus negative. In this case, the stone material enterprise to avoid all sorts of additional advertising budget, reduce brand promotion, etc, and to reduce financial crisis to bring adverse effects. Special circumstances, the careful and strict market decision is understandable, but no and brand construction is a long-term and sustainable construction process, related to the further development of enterprises and expands, therefore, special circumstances, reduce enterprise, product brand publicity is questionable.
1, advertising purposes
Successful enterprise concerned enterprise and media relations, they rely on media. This aspect is backward, in stone industry in the media over there “light shout”, and lack of enterprise and the whole industry supports. Should say media advertising is stone supplier of marketing is an important link, he is not only the expenditure and investment, he is the intangible asset of a kind of important means to accumulate. Many stone enterprises that the advertising expenses is the enterprise marketing expenses, so in the shortless of market, the first thought of advertising and publicity is to reduce spending. Actually, the ads just give the parties may provide a, let them know you product demand and points to the value of stone enterprises.
In the financial crisis and under the influence of the market, stop and reduce expenditure, not only make advertisement purchasers and consumers understand your product information, and produces daydream. “,” At the same time, the author thinks that the financial crisis in the future life is the uncertainty, if the stone enterprises in the back or change the propaganda strategy selection, the consequences will be affected.
2, the brand advertising to grow steadily
Stone brand, enterprise, outstanding success brand also number. But to aspire to bigger and stronger brand of stone enterprises, more particularly important, stone material enterprise have been positioning for “dirty, and poor”, so the stone material enterprise brand construction is a long and arduous process, no hesitation and retreat. If when the beginning or maintain or even enhance brand promotion, more leader.
At the same time, the stone material enterprise brand publicity is through a lot of stone exhibition, the greater the booth or whether in the country and abroad each big stone exhibition is weighed the stone industry is an important form of the position. In this crisis, in the promotion of brand of the more homework, the purchaser is to show enterprise and confidence, along with the market situation, the economic recovery, the spread of value or through sales.
3, stone material enterprise in the face of difficulties “survival”
Often hear the stone industry, the competition is intense, low threshold serious influence the development of the market situation, with the increasingly serious, will appear a series of changes in the threshold and risk, further deepen brand concentration, further highlights, a strong brand “, “sweep wind, survival in the face of difficulties of particularly outstanding performance.
Brand as he who does not advance loses ground. China stone industry is a competitive market opportunities, challenges and chances, and every enterprise, and the key is to see who insist on taking place, a brand publicity and expansion.
Mr Ma said: “today, tomorrow is cruel cruel, very nice, but most people died in tomorrow night, see the sun!” Before doing about the 2009. “No,”, “continued development, want to add two solutions” side of 85%, “Confusion”, “collapse” two sum is about 15% of financial crisis, so the stone industry influence may not imagine so big, also nothing terrible, the stone material enterprise has the ability to easily cope with the crisis, and the economy of China stone industry and the sun came to see.
A national rare ore reserves of brown granite has appeared large in Hami City.
It is reported that the newly discovered brown granite total of three fineness, slightly brown granite the most good, hard stone, color uniformity, pattern harmonious, high gloss, high-quality stone blocks can be used as a conservative estimate the reserves of nearly 4 million cubic meters , at least 100 years of mining. It has attracted the close attention of some large enterprises, and to the parties concerned to apply for mining permits.
Yesterday morning, laizhou yantai international convention and exhibition center, vice mayor of peace to waiting outside to thousands of participants, announced the 14th international stone exhibitions. Participants lined up bumper, orderly into the convention and exhibition center, this case has run from 2003, the seven times the annual international stone exhibitions became the laizhou stone field.
Stone exhibition industry has the tentacles of stone
Reporter met Mr Yoon, he took two stone samples from hebei, Mr Yoon a mining enterprise, just saw the local customers, conveniently see stone exhibition, through the economic crisis industry trends.
Mr. Even from fujian province, is a stone machinery enterprise laizhou base of their base was established in 2001, “this machine has been sold out!” Mr. Even as a large equipment, told reporters. Mr Dai also represents a stone machinery enterprise of southern shandong laizhou base, says Mr Dai, laizhou base of Beijing, Inner Mongolia, radiation liaoning, jilin, etc, very big market.
Laizhou local wang, manages selling stone industry chemical products in the company, he says, the customer business has been very fire is some mining enterprises, economic crisis of his basic enterprise have no effect.
Some of the areas of shijiazhuang abrasive company representative Mr. Hou said, they have been continuously for several years, this year small-and-middle size of the exhibition, the exhibitors than ever, to the participants can better communicate with the colleague, understand the industry trends. They are the workers, the grinding stone before the exhibition.
“Large scale, exhibitors more”, this is the most people in the stone exhibition booth, and over a 617 stone upstream to downstream of each link, formed a complete coverage of the stone.
In local extensions, reveal tentacles characteristics of local space-unit
Mr Section is a stone laizhou summer high town space-unit company responsible with confidence, he tells a reporter, the company has thousands of stone, with few other type of local companies can exceed the amount. Mr Period for the company to operate import stone, already developed now become started integrating mining, wholesale, man-made stone processing as a large china stone suppliers. This is the stone industry high laizhou summer a microcosm of summer, according to statistics, high current stone processing enterprise, employees more than 1700 3.2 million.
According to the introduction, the second part of the local space-unit, after the end of the exhibition will be fixed to a long-term, the display window. This stone is local booth, a feature of the exhibition, the local characteristics of various space-unit, left a deep impression to the participants.
Touch stone downstream enterprises, starting a new nuggets action
The exhibition is a beautiful scenery, female artist playing elegant guzheng, guests in the atmosphere in the mini-sculpture taste Chinese tea. Beside a booth, a stone was selling books. Stone material culture, may represent the next phase of the stone laizhou the development direction of the nuggets to downstream.
Guangdong stone industry association, said this exhibition HuangZeHong impressed him deeply, apart from the local advantage, derivatives in exhibition can see clearly, this is stone industry laizhou, he thinks, industry and local laizhou in brand shaping, remains to be strengthened. HuangZeHong President told reporters the stone, the development space of upstream can have is not very big, but such as engineering and maintenance of downstream of the stone material culture, even a great development, in addition to the new techniques such as composite panels, ultra thin applications. “The great value of the downstream extensions can, at least in the existing basis to improve more than 1/3!” HuangZeHong with confidence is expected to grow.
Earlier this year, longjiang town, shunde district, foshan city, guangdong province, north section of a lot more transport vehicles in stone. Originally, because such stone furniture collocation marble recently began flourishing, many manufacturers have opened a new to the purchase raw material market. The market scale of attraction lies in its.
The sale of stone, longjiang are scattered, mostly shops are family business, not only the product category designer and surrounding environment, caused great influence. In April, the situation began to change in longjiang town, a stone furniture, covers an area of 50,000 square meters large decorative materials city formally opened.
According to the material city controller introduces, this stone market is April preparation, outdoor and indoor is divided into two parts. Open the stone market covers an area of about 2 million square meters, more than 30 shops are all in, 3 million square meters of indoor unit is also attracting, but here, more than 1,000 tons of stone material flow. Here are all the stone is peculiar, henan nanyang, furniture, building materials of high quality made of stone, coming here to do business is henan nanyang 90% of people.
It as a material, furniture, furniture stone hasn’t been categories of people’s attention, in every large furniture material market has not into the exhibition venue, in scale and furniture material exhibition in edge position more desperate. However, with the flourishing, annatto furniture and household vogue miniascape wait advocating nature of furniture, cooperate concept of furniture are made of stone of their spring, and also for furniture makes a new stone market.
Longjiang as China furniture material, furniture manufacturing, material is very prosperous developed markets. But because the market most scale longjiang stone, scattered in the old 325 national road longjiang section and lung chau north road sets. Today, the large furniture gradually arisen, scale stone market is growing. Now the furniture material is very extensive, furniture market of stone material can not only meet the needs of furniture, and expanded the categories, longjiang furniture material of shunde furniture industry diversification is very good.
Now, except for the Asian longjiang international furniture material trade center, handsome, longshan materials, materials, asia-pacific wood furniture material four big cities, and more professional market has a large stone market, professional furniture to boost in the market have a pen.
On June 11, nanan shuitou planning (2010-2030) through the expert, as quanzhou city in the south, the head of the centre will be built into the international stone headquarters.
The scope of planning for the head 127 square kilometers, and 2030 about 40 million population size.

Early yunfu known as “stone is that” reputation, for many years, the first stone production at the first varieties. Recently, the reporter, product line of yunfu came here stone “buy the world” and “sell” of the world.
“The stone with corridor”
Driving in yunfu 324 national highway, but saw walking on stone corridor “, “inside a busy, shop next to a, greatly small natural stone man-made stone, spectacular in aircraft. According to introducing, the stone, have certain yunfu scale enterprise is more than 3000, the annual output reaches more than 40 million yuan. We came to the general new building material Co., LTD, here is the product with man-made stone. Raw material is mainly is those deemed to be cutout, even waste rock, after crushed and chemical raw materials, again become a wide range of applications, the price of the new building materials, inexpensive, recycling and dual efficacy of environmental protection. According to company boss, because they produce, process of man-made stone in the hardness, wear resistance aspects even better natural stone, and also more varieties. Production site has several large grinding equipment running. Ask know, equipment imported from Italy, is now the most advanced an automation equipment. At present, the small factory “Ervin” produce man-made stone, has been used in the domestic many large-scale projects, such as Beijing MeiDeYa news centre, Hong Kong station, the butterfly trench porch, etc.
Recycling waste material processing
With the general production man-made stone have other is local and batch processing of natural stone material enterprise, enterprise is a brother and light. “Welcome” into factory, we first is capacious yard on a neat rows of huge stone pieces, each piece is sufficient several tons, some “big” is weighed hurling tons. In this factory work nearly 20 years of LiangXiaoJie tells us that these stone comes mainly from Italy, Russia, India,… Local some stone quarry in foreign boss has bought back to the mining, stone, processed in yunfu aggravate shipped around the world. In the enterprise product showroom, we saw many European building stone products and crafts, such as the fireplace, lavabo, stone desk clock, etc. These products are sold abroad, will sell well.
From Italy imported automatic grinding equipment
Locals, are all now yunfu stone from all over the country, and even in the world, into new products, yunfu again to sell all over the world. So, today is worthy of yunfu stone “buy” and “sell the world”, thus make piles have many!
Artificial stone, which by definition is not 100% made of natural stone processing stone materials. Their production methods can be divided into two kinds: first, the raw material ground into powder, then adding chemicals, sticking agents, made of high pressure plate, and in appearance and color, add artificial coloring and imitation of the original stone lines to improve varied and selective. The other is known as the man-made granite, stone is broken after the original by adding a vacuum resin and stone mix, and ways to make use of high-pressure shock shape, made of a block of rock, and then after cutting a stone building materials; except retains the natural texture, it can advance through the selection of uniform colors, and adding a favorite color, or embedded in glass, acrylic, etc., to enrich the color diversity.
Common materials for indoor decoration to have granite, pearl shell and sand culture stone, its hardness is not as hard as natural stone, and there is a clear difference in texture. However, because of the price much lower than natural stone, and the use increasingly common, especially with 90% of the natural synthesis of the original granite stone, natural stone easily overcome break the lack of texture not easy to control, retain the original flavor of natural stone in the world the market place, or even replace marble, granite flooring usage trends
Two major types of natural stone: marble, and granite. In general, where there are texture, known as the “marble”; to Point Ban-based, called “Granite.”This is a broad sense.In a narrow sense, the marble that is produced in Dali stone. In fact, not many around the country out of stone is marble.
Both can be distinguished from the geological concept. Granite is igneous rock, also known as acid crystals Plutonic is the most widely distributed in igneous rocks of a rock, the feldspar, quartz and mica composition rock hard dense. The silica-based components, accounting for 65% -75%.
The so-called underground magma igneous rock is volcanic eruption or lava rock cooling crystals formed.Igneous rocks in silica content, the nature and content of feldspar determine the nature of stone. When the silica content of greater than 65% belong to acid rock, this rock CKS feldspar, plagioclase, quartz crystals and other basic mineral formation, were expected to like structure, known as granite.
Marble is the crustal rocks through the crust in the Central Plains and some high temperature and pressure of metamorphic rock formed.Internal forces to promote the role of crustal rock types of the original qualitative change, that the original rock structure, structure and mineral composition change. After the formation of a new qualitative change is called metamorphic rock.
Marble is composed of calcite, limestone, serpentine and dolomite composition. The main ingredient in calcium carbonate and account for about 50%. Because marble is generally contain impurities, and calcium carbonate by carbon dioxide in the atmosphere, carbon, the role of water vapor, but also easy to weathering and erosion, Er Shi surface quickly lose their luster. Relatively soft marble of a general nature, which is relative to the purposes of granite.
Because of natural stone are porous, so the relative difference in the stain resistance of some areas, usually in the processing plant will be on the surface for processing. In interior decoration, the TV table, windowsill, indoor surface such as marble for use. The threshold, the cabinet table, suitable for use outdoor ground granite. Taiwan cabinet which is a good concept is the use of dark granite.
Now on the market of natural stone, part of the color is through manual processing, these stones will generally use the six months to a year, revealing its true face. Is clear that the market is now big flower green, many of which are made of stain, not the real colors.
Also note that the back of the grid, this happens in two ways:
① stone itself is brittle, must add grid, such as Spain beige.
② jerry, the thickness of these stones is thinning, and strength enough, so I added a network. Generally darker style of stone if the majority is for this reason.
Artificial stone is unsaturated polyester resin as the binder, together with the natural marble or calcite, dolomite, silica sand, glass powder and other inorganic powder and appropriate amount of flame retardants, color, etc., by mixing ingredients, porcelain casting, vibration compression, extrusion and other methods of forming curing made. Artificial stone is based on actual use of natural stone to finding out the problem, and it is moisture-proof, anti-acid, high temperature, put together have made great progress in terms of. Of course, man-made things are man-made natural disadvantages, the general nature of man-made stone is obviously inadequate, the texture is relatively higher than leave, so be used for cabinets and other high places for the practical requirements, and some harsh environments, such as kitchens, toilets, etc. ; bay windows, decorative floor and so stressed areas, are used less.
Another factor impeding the use of artificial stone is the human factor.As the man-made stone very different production process, performance, features do not correspond exactly to the advantages mentioned above does not set that you purchased the performance of artificial stone. Imports of man-made stone currently on the market is better in performance. Such as imported marble allows sanding scratches the surface, the user does not reassert itself to handle it met, and many made of artificial stone obviously can not support this flow of talent, the more polished the more rotten.
Buy artificial stone, it is best to acquire a piece of bad test sample, such as soy sauce or oil down as well as extravagant loss test. To sum up, what what kind of stone purchase, according to places, use different and personal financial capability.
Finland is also a small amount of imported natural stone, in 2002 approximately 11 million U.S. dollars of imports, exports less than 13%. The main importing countries are Italy (more than 35%). The number of imports from China, rapid growth, and accounted for 29% of Finland’s total imports. Followed by Italy after China and is expected to surpass Italy in the near future. Output of a large number of Finnish granite, and new granite deposits are constantly developing. In the next few years will be more committed to the development of new deposits. Stone products for the presence of radiation problems, further enhancing the detection, in the mining process, the attention to green mining to ensure the health and environmental protection products. In Finland, most of the stone is small and medium enterprises, family-owned businesses. So these companies need is close cooperation to optimize the use of their technology, this demand is increasing. Businesses in this area, mining and processing equipment manufacturers, research institutes and various training institutes in close cooperation between the need to further improve. Objective is to generate a field for the “industry chain”, in order to better meet the needs of the growing number of buildings, and through their own efforts to promote the development of environmental architecture. This close cooperation will be the application of stone to produce more new solutions.For example, cold winter in northern Europe, in some appropriate area to build warm stone-built pedestrian streets.
