摘　　要：大红山铁矿是一座特大型的露天地下联合开采矿山。针对崩落法开采厚大缓倾斜深部矿体导致的上覆岩层与地表地质灾害,提出并实施了一整套相应的综合防治措施,包括上覆岩层微震监测系统、沉降变形实时自动监测报警系统,地表变形监测系统,以及主采区顶板硐室爆破强制落顶、地表塌陷范围警戒和塌陷坑回填治理措施等。通过综合防治,有效避免和消除了上覆岩层的工程与地表地质灾害,取得了安全生产的良好效果。Dahongshan Iron Mine is an oversize open underground combined mine. The caving mining was used to stope the large and slightly-inclined orebody, which caused geological disasters in overburden and surface. Aimed at these problems, a full set of comprehensive control measures was proposed and implemented, including the microseismic monitoring system, the real-time automatic monitoring and alarming system for subsidence in overburden, the surface deformation monitoring system, the chamber blasting for forced caving roof in main panel, the warning area of surface subsidence, and the backfill for collapse area. Through comprehensive control, the geological disasters in overburden and surface were effectively avoided and removed, which ob- tained good effects on safe production.
