Study On Technical Guide For Locale Environmental Supervision In Coal Mine Enterprise

China is the largest coal producer in the word, coal production reach 1/3 of the total coal production in World.31 provinces in Mainland China, except Shanghai, have proven reserves of coal resources, most of them in North China. The occurrence conditions of coal resources and historical reasons which decide the existence of a large number of coal mining enterprises of small and medium.Underground mining and Open-pit mining way are used to develop coal resources. The wet way is adopted to Washing coal adopts, Heavy medium coal separation method is used widely.Coal development impacts on the environment including pollutants and ecological damage. Environmental Impact, such as soot and SO2 emission from coal combustion, coal dust produced by Processing storage and transportation of coal, Coal Mine Gas Drainage, Harmful gases such as CO2,SO2,CO produced by Spontaneous combustion of coal gangue; Water Environment is impacted by Mine water,wasted water which washing coal; Coal mining on the ecological environment mainly affects the destruction of the resources of land and groundwater.For the environmental impact of coal development, appropriate environmental protection measures are used by Coal Enterprises. Boiler flue gas uses Wet desulphurization and dust removal technology, the efficiency of Elimination dust can be reached to 95%-99%, the efficiency of Desulfurization general can be achieved to 60%-80%; Usually, Add bag filter dust mask is used to handle or process of dust generated by screening, the efficiency of Elimination dust can be reached to more 99%; Coal mine gas as a fuel is utilized, such as used by their own or Power Generation; Mine water passed Coagulation, sedimentation, filtration, disinfection to Underground; wasted water which passed "Cyclone-Thickener-Filter (Sludge sedimentation tank)" to achieve closed loop. Coal Mining tremendous impact on the ecological environment, may lead to surface subsidence or Falling water tables, etc, the measures of Reclamation, green are always adopted to recovery Ecological.In addition, another way to solve the environmental problems of coal enterprises is strengthen supervision and management, this mainly rely on the effectiveness of environmental monitoring, but now, Environmental monitoring of coal enterprises is Lack of normative, theoretical guidance documents, so drawing up《Technical Guide for Locale Environmental Supervision in Coal Mine Enterprise》is Pressing.At first, the Technical framework of guidebook is studied, main content include relevant laws and regulations,Industry standards,Locale Environmental Supervision in Coal Mine Enterprise, etc, proposed the outline of《Study on Technical Guide for Locale Environmental Supervision in Coal Mine Enterprise》, indicated the focus of production site environmental monitoring, Monitoring points of pollution control measures. Finally, the Single detail of Locale Environmental Supervision in Coal Mine Enterprise is draw up.Limited by site investigation and incomplete information around the coal enterprises, environmental protection measures,methods and monitoring points which were used may be limitations, so, the process of guidelines to be prepared to further improve in the future.
