Abstract: According to the condition that the gas emission is large on during tunneling, initial mining, end mining for west 3^# working face in Puhe Coal Mine, the various means of comprehensive management to control gas in the period of tunneling, end mining, the pre-pumping is applied in the tunneling working face. In the fully mechanized caving face, the high gas pumping is carried out by the means of deep buried pipe and long distance, and the low gas drainage is conducted through the method of shallow buried pipe and near distance, which achieves remarkable results and ensures safety production.
