毛坪铅锌矿在采矿活动中，地下空区发生了垮塌，导致矿区地表边坡出现多处塌陷坑及裂缝，危及了地表的安全，影响了井下矿体的回采。对山坡坍陷开展工程地质调查，并分析其成因，提出井下塌陷空区采取充填及封闭处理，对地表塌陷坑进行高、低压注浆加固固结充填体，并清理地表危岩。采用数值模拟的方法，进行了空区治理前及空区治理后的稳定性对比分析。分析结果认为矿山采用的治理方法能够保证矿山地表稳定，保障矿山深部矿体的安全开采。

Underground mined‐out area collapse caused by mining activities in Maoping lead‐zinc mine leads to surface subsidence and cracks ,endangers the safety of surface and affects the mining of orebody .A series of treatment measures which include filling and closing collapsed mined‐out area ,reinforcing filling body by using high and low pressure grouting from surface and cleaning up the dangerous rock on the surface have been adopted to control mined‐out area .Stability analysis and evaluation are carried out for the situations before and after the treatment of mined‐out area by using numerical simulation .The analysis results considers that the treatment measures adopted by Maoping lead‐zinc mine could guarantee the stability of surface and safety mining of deep orebody .
