摘要
红透山铜矿深部矿体探明后 ,60年代建设的主井在其预计开采崩落范围内。针对压矿量数百万吨的保安矿柱 ,矿山根据安全开采深度理论在系统空区中构筑人工胶结隔离层并加强空区充填 ,大大缩小了围岩崩落范围 ,释放了积压矿量 ,保证了竖井安全。
The locating of the deep ore body in Hongtoushan Copper Mine showed that the main shaft build in 1960s was in the predicted caving scope.In view of the safety pillars which had stored several million ton ore and according to the theory of safe mining depth,an artificial isolation layer was constructed in the mined area and its filling was strengthened so as to reduce the rock caving scope,liberate the stocked ore and ensure the shaft safety.
