摘　　要：针对同忻矿8102双侧小煤柱孤岛综放工作面在回采过程中存在的强压力显现的问题,通过采取卸压钻孔、起底、开卸压槽、补强永久支护、加强超前支护等措施,实现了压力卸载与释放,加强了工作面的支护强度,有效避免了工作面发生强矿压灾害。In view of the problems of strong pressure in the mining process of the 8102 small coal pillar isolated island fully mechanized caving face in Tongxin Mine,the pressure unloading and release are realized by taking measures such as pressure relief drilling,bottom lifting,opening and unloading groove,reinforcing permanent support and strengthening advance support,strengthening the support strength of the working face and effectively avoiding the strong mining pressure disaster in the working face.
