摘　　要：针对华亭煤电公司砚北煤矿缓倾斜特厚煤层开采时的强矿压显现现象及特点,测试研究动力灾害机理,采取电磁辐射、微震监测、钻屑法、爆破卸压、煤岩层注水等综合防治措施有效控制和削弱矿压显现强度,取得了较好的防治效果。Aiming at strong underground pressure behavior and its characteristics in full-mechanized caving mining extremely thick and softly inclined coal seam in Yanbei Colliery of Huating Coal ＆ Power Corporation, this paper applied test method to researching mecha- nism of dynamic disaster. Comprehensive prevention methods ineluding electromagnetic radiation, micro-seismic monitoring, drilling chip method, blasting relief and water-injecting were adopted to effectively eontrol and decrease behavior of underground pressure. Good prevention effect was obtained.
