摘　　要：针对缓倾斜突出煤层石门揭煤发生突出的特点,结合焦作矿区二1煤层揭煤的大量研究与实践,确定了以石门短导硐震动爆破配合交叉钻孔强化卸压抽采为主的缓倾斜突出煤层石门揭煤技术,实现了冯营矿2415车场、2417车场的安全揭煤,为矿井合理采掘部署提供了保障。For the characteristics of rock crosscut coal uncovering outburst in gently inclined outburst coal seam, and combined with nu- merous studies and practice of Ⅱ 1 coal uncovering in Jiaozuo mining area, determining the coal uncovering technology which through short pilot tunnels shock-blasting with cross borehole pressure relief gas drainage in gently inclined outburst coal seam. Achieved safe exposing coal in 2415 and 2417 yard in Fengying Coal Mine,and provided protection for mining deployment reasonably.
