Abstract: According to the characteristics of the contiguous coal seams group in Wuhushan Coal Mine, based on the analysis of the gas occurrence and emission laws and the calculation of the amount of gas emission in the working face, the seperating source control technology suitable for the mining of the gassy contiguous seams group was put forward, including "the regional gas pre-drainage by directional long holes, the gas drainage by pressure relief of the adjacent layer, and the gas drainage from gob". The application of this technology has resulted in effective control of the mine gas emission and ensured the safe and efficient production of the working face.
