摘要
在这一采矿方法的研究和实践过程中，结合矿山实际情况，从理论分析和室内试验入手，采用进路分层充填结构、黄泥接顶、承载层不设吊筋和锚杆、溜矿井用密集木框支护、无掏糟爆破等项新技术和新工艺，降低了水泥和钢材消耗，简化了工艺流程，改善了充填接顶和爆破效果，提高了生产能力。该采矿方法已在生产中推广应用。
Combined with the mine reality closely , to start with the theoretical analvsisand the laboratory experiment , in the process of resrarch and practice in this miningmethod,the new technology such access slicing structure ,roof contacted with loess,loadedlayers without cables and rock bolts ,ore passes with close timber square seta,and no-cuthole blasting etc. was used to reduce the consumption of cement and steel,simplify thetechnological process, improve the effectiveness of both roof contacted with filling andbladting, and increase the production capacity. This mining method has been deployed inthe mines.
