摘　　要：随着东塘子-铅硐山铅锌矿开发工程推进,井下采空区增多,严重影响和制约矿山采矿生产进程。分析了采空区分布现状,总结了前期充填试验的经验和教训,提出后续回采及采空区充填建议。通过分析深部资源开发、采空区充填方式和充填物料,以延深小的独立铅锌矿体为首采地段,为井下废碴充填提供空间;再对陡倾斜、延深大的翼部矿体进行独立分段,并在分段内由下向上逐层回采并充填采空区;最后对鞍部富厚矿体分批次间隔式开采并充填采空区。通过采空区充填,达到减轻井下地压危害,实现资源高效开发和废碴综合利用的目的。With the advancement of the development project of Dongtangzi-Qiandongshan lead-zinc mine,the underground goaf increases,which seriously affects and restricts the mining production process of the mine.The distribution status of goaf is analyzed,the experience and lessons of previous filling test are summarized,and suggestions for subsequent mining and goaf filling are put forward.By analyzing the deep resource development,goaf filling method and filling materials,the independent lead-zinc ore body with small extension depth is taken as the first mining section to provide space for underground waste slag filling.Then,the steeply inclined and deeply extended wing orebody is independently segmented,and the goaf is mined and filled layer by layer from bottom to top.Finally,the saddle rich and thick ore body is mined in batches and filled with goaf.Through the filling of goaf,the harm of underground ground pressure is reduced,and the purpose of efficient development of resources and comprehensive utilization of waste slag is realized.
