Now the coal mine gas risk index and evaluation system has a lot of deficiency. The paper establishes a coal mine gas risk index system and explains the meaning of each index on the basis of analysis of gas accident for recent years. Fuzzy comprehensive evaluation has become an effective and popular method, so the paper evaluates the coal mine gas accident risk using fuzzy mathematical safety evaluation, and takes this method in six mines of one group, at last the paper provides some suggestions for this method

Coalbed methane (CBM) resources are abundant on the earth. CBM brings man-kind harm but its also a clean type of resource. This article based on the analysis of CBM exploitation and utilization at home and abroad, analyzed the key issues for the slow development of CBM industry in China combining the domestic practical situation of coal mine gas drainage, and also proposed suggestions of reasonably exploiting and utilizing CBM.

Coal gas is a key factor in coal mine production safety, gas outburst and other threats can cause suffocation mine operating personnel, damage to human health, the gas reaches the ignition and combustion gases can cause encountered gas and coal dust explosion; while the main gas or the Earth's atmosphere sources of pollution. Therefore, effective governance gas to gas as a resource to achieve coal and gas extraction, to eliminate sudden end, and take advantage of the gas, reducing its air pollution is a major issue in the field of coal mining, the paper gas utilization, gas drainage aspects of mining, mine gas drainage system briefly described.
