Abstract In order to realize the efficient control of gas in Sihe Coal Mine, this paper puts forward the combined extraction technology of upper and lower wells according to the characteristics of coal seam gas occurrence in Jincheng Mining Area. The current situation of combined gas extraction technology in Jincheng mining area is analyzed, and the occurrence characteristics of coal seam gas are analyzed. Based on the time-space replacement law of coal development, the coal mine area is divided into three intervals : coal production planning area, coal development preparation area and coal production area. In terms of time, it is reflected in the implementation of surface well pre-drainage in coal mine planning area, the implementation of combined drainage in coal mine preparation area, and the implementation of underground gas drainage in coal mine production area. Taking Sihe Mine as the background, the field practice was carried out, and the risk of coal and gas outburst was finally eliminated.
