Abstract
Coal mine gas disaster is one of the major disasters in coal mine production,which needs to take targeted measures to prevent.The gas content in the overlying strata of the high gas mine and the high outburst mine in the coal seam of Yangquan mining area is high.Only the gas drainage of the coal seam can not effectively solve the gas problem during the mining.Therefore,this paper took No.3105 Face of Xinjing Company as an example to study and apply the construction technology of gas drainage drilling holes in overlying adjacent rock strata.The practice showed that the application effect of this technology was good,the gas extraction rate was high,and the high drainage roadway project was replaced within a certain range,which saved the production cost,alleviated the connection of working face mining,and ensured the safe production of working face mining.关键词
