Coal Gangue Promote Environmental Protection First Mill Utilization

Recently reported , Fugu County, Shaanxi discovered large coal origin, reserves of over 5.6 billion tons . It is understood that exploration and exploitation of the discovery of large coal origin lasted three years , the coal seam thickness, coal quality is good , simple structure, suitable for the construction of several large mines, is expected to become the largest in Shaanxi Province with coking coal base. At the same time we know that coal use is widespread , can be summarized into two main purposes in accordance with its intended purpose : ( 1 ) thermal coal ( 2 ) of coking coal .

But in the process of development of coal , the major impact caused by waste material , such as the environment and the sustainable development of the country and the world. Coal enterprises in the long-term exploitation of coal resources in the process , there are often ground subsidence, gangue waste area , sewage , predatory exploitation , mining accidents and other negative phenomena , caused severe resource depletion and environmental damage.
With the continuous deterioration of the socio-economic development and environmental conditions , environmental costs began to receive attention in the search for demographic, economic, social, environmental and resource coordination , both to meet the needs of contemporary people but does not meet the needs of future generations path of sustainable development capability pose a hazard in coal mining environmental issues is very important.
Recently, some learned that many coal companies or investors have begun to make use of technology and processes waste gangue turning waste into treasure . Classes with the use of a mine waste material processed mine waste rock generated during tunneling underground with cement road pillow , tail cones and gunite cement row with gangue powder for...
