摘要
结合马坑矿区中矿段西区+360^+420m14#矿块的回采设计以及现场的技术管理、指导经验,介绍了无底柱分段空场采矿、适时崩落顶板围岩充填空区采矿法在马坑矿区的应用,分析了马坑矿床特点以及无底柱分段空场采矿、适时崩落顶板围岩充填空区采矿法的采矿工艺。
Combining with the stoping design and the site technical management and guidance experiences of the 14#ore block stoping of+360^+420 m middle levels in west area of Makeng Mining District,the pillarless open stope method and caving of roof rock timely to fill up the mined goaf are applied in Makeng district.The Makeng deposit characteristics,the pillarless open stope method and caving of roof rock timely to fill up the mined goaf mining technologies are analyzed.
