Abstract
Gas drainage is an effective measure of solving mine gas disasters,and rational using of resources.According to the technical requirements of gas volume fraction control in high gas mine gas drainage systems management control,through the cause analysis of the drainage concentration that the gas can not meet the design requirements,the reasons why gas concentration is generally low efficiency in drainage system,which caused decreased drainage are summarized.Combining the gas geological conditions of Chengzhuang mine,reasonable improvements and solutions in sealing materials,hole process,drainage,etc,are made.
