Since the founding of the People’s Republic of China, under the guidance of the party and the state on the principle of protecting natural resources and safe production, the vast number of staff and workers of coal mines have made concerted efforts and made great achievements in the development and utilization of coal mine gas resources. In the national coal mines, the amount of drained gas and the scale of its development have been gradually increased and expanded. Of the key coal mines in the country and part of the local mines with high biogas, 101 mines have been set up for gas drainage and there are over a dozen pairs of mines under construction Drainage system, most of these mines to achieve normal drainage, the amount of gas extracted from the early liberation of 20 million meters to 3, increased to 270 million m3, an increase of more than 12 times. Gas drainage technology
