摘要

There are many problems in terms of safe coal production and the sound de-velopment of the coal industry. Accompanying the intensification and increasing efficiency of coal production and the conducting of mining operations at deeper and more remote areas of mines, the efficient recovery and utilization of Coal Mine Methane (CMM) is an important issue in improving and stabilizing the productivity in the coal mining industry with high levels of gas, where the incidence of gas outbursts is increasing. We plan to study various aspects of the development of production technology and characteristics of the mine site. This is to establish the technology for highly efficient coproduction coal and gas operation rate. As a result, the productivity at the coal mine face will increase due to the reduction in gas emissions in the mining face. Effective use of recovered gas can be ex-pected to reduce global warming by reducing the amount of coal mine methane gas emis-sion in the air.
