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。
After the deep ore body of the Hongtoushan copper mine has been proved, the main shaft built in the 1960s is within the range of the expected mining caving. According to the safe mining depth theory, the mine constructs artificial cementing isolation layer and strengthens the empty area filling according to the theory of safe mining depth, greatly reduces the surrounding rock caving area, releases the backlog of ore amount, guarantees Shaft safety.
