摘　　要：目的:复杂老旧隐蔽采空区的治理一直是空场法开采矿山面临的重大难题。柿树底金矿为了解决大面积、多中段、已塌陷老旧隐蔽采空区的安全治理问题。方法:通过采空区禀赋特征调查,开展了高阶段大跨度塌陷采空区似膏体非胶结充填治理技术研究与工程应用实践。结果:采用非胶结全尾砂充填治理采空区,消除了老旧隐蔽采空区的安全隐患、防止了地表的继续沉降和塌陷、避免了大规模地压灾害事故。结论:非胶结全尾砂充填治理采空区研究对于减少矿山运营成本、实现矿山固废零排放具有巨大的经济与社会效益,为国内广大空场法开采矿山的采空区治理提供了借鉴。Purpose:The treatment of complex old concealed goaf has always been a major problem in open-stope mining.To solve the safety management problem of large area,multi-middle section,and collapsed old hidden goaf in Shishudi gold mine.Method:Through the investigation of the characteristics of goaf,the research and engineering application practice of paste-like non-cemented filling treatment technology for the high stagelarge-span subsidence goaf was carried out.Result:The non-cemented full tailings filling was used to control the goaf,which eliminated the hidden safety hazards of the old hidden goaf,prevented the continuous settlement and collapse of the surface,and avoided large-scale ground pressure disasters.Conclusion:The research on the treatment of goaf by non-cemented full tailings filling has great economic and social benefits for reducing the operation cost of the mine and realizing the zero discharge of solid waste in the mine,which provides a reference for the treatment of goaf in the majority of domestic open stope mining mines.
