摘　　要：针对中家山铅锌金银矿马山采区前期浅部民采活动遗留的空区隐患问题,开展了浅埋民采空区综合探测与治理方案研究工作。为避免民采空区次生灾害发生并消除与井下生产相互影响,基于瞬变电磁法探测技术手段对空区进行初次物探,在初次物探空区成果基础上,有针对性地布置定向钻孔进行无差别探测,准确掌握了民采空区的数量及位置分布。根据民采空区分布特征和周边生产现状,经过分析比较,选用尾砂胶结充填进行治理,既能消除民采空区隐患,又能保障井下安全生产,同时为类似矿山提供了实践经验。In view of the hidden danger of goaf left by the shallow mining activities in Mashan mining area of Zhongjiashan Lead-zinc-gold-silver Mine,the comprehensive detection and treatment scheme of shallow buried mined out area was studied.In order to avoid the occurrence of secondary disasters in the mined out areas and eliminate the mutual influence with the underground production,the first geophysical exploration of goaf based on transient electromagnetic method was carried out.On the basis of the results of the first physical exploration area,targeted directional drilling for undifferentiated detection,the number and location distribution of the mined out areas are accurately mastered by the directional drilling for non discrimination detection.According to the distribution characteristics of the mined out areas and the surrounding production status,by analysis and comparison,using tailings cementation for filling treatment can not only eliminate the hidden danger in the mined out area,but also ensure the safety of underground production.At the same time,it provides practical experience for similar mines.
