Discussion on Ways of Mine Gas Drainage and Extraction

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.
