摘　　要：经小煤矿破坏后的煤层,很难进行回收开采,因此造成了很严重的资源浪费。为了响应资源整合的政策以及对于矿井兼并重组前小煤矿采空区遗留的煤炭资源统计,分析了小煤矿存在的采空区的各种遗煤形式,以某矿区为例针对柱式采煤空巷、壁式采煤空巷等遗煤形式分别采用与其相适应的复采技术,结果表明对兼并重组的小煤矿采空区遗煤进行复采技术可行。The coal seam destroyed by the small coal mine is difficult to be recovered and mined,thus causing a serious waste of resources.In response to the policy of resource consolidation and the statistics of coal resources left over from mined-out areas of small coal mines prior to mine mergers and reorganizations,various mined coal forms in mined-out areas of small coal mines were analyzed.Taking a certain mining area as an example,the corresponding coal mining technology is adopted for the pillar coal mining roadway and wall mining coal mining roadway.The results show that the coal mining technology in the small coal mine goaf area merged and reorganized feasible.
