Abstract: When mining coal seam group in prominent mine,in order to effectively prevent and control the risk of coal and gas outburst and ensure the safety of the Ji_16-17-14060 working face coal seam group mining in Pingmei No.13 Coal Mine it is necessary to adopt mining protective layer measures to prevent and control outburst and select a reasonable and feasible first mining protective layer.Based on the basic principles of selecting and mining protective layers,this paper discusses and compares from five aspects such as the mine coal seams occurrence situation of the Ji_16-17 coal seam and Ji₁₅ coal seam,the danger degree of coal and gas outburst,the mining effect of protective layer,whether the mining conditions of the protected layer are damaged,and the economic benefits.The results indicate that selecting the Ji_16-17 coal seam as the first mining protective layer in mine is relatively reasonable.A protective layer selection model is constructed using the method of Analytic Hierarchy Process （AHP）,which further demonstrates the feasibility and rationality of using the Ji_16-17 coal seam as the preferred protective layer for mining.This model plays an important role in the safety production of the working face in Pingmei No.13 Coal Mine,and provids a reliable basis for the safe mining of the mine.
