Mine gas accidents seriously affects safe mining. With the research and exploration of mine gas prevention and control, the treatment of mine gas prevention and gas accidents is getting more mature. In order to prevent mine gas surge accidents, gas drainage technology was adopted to prevent mine gas accumulation. Through the gas emission from the 1303 working face of Licun Mine, the corresponding gas prevention measures were proposed. The increased mining depth of the mine led to the deterioration of the permeability of the coal seam, which affected the gas drainage efficiency of the mine. In this case, the low permeability gas drainage technology of the coal seam was studied, and the gas drainage technology of the low permeability coal seam was summarized to provide reference for the follow-up project.
