摘　　要：某小型萤石矿已开采多年,由于井下采空区分布比较分散,部分老采空区资料缺失,且矿山对采空区分布情况了解尚不全面,严重影响矿山生产安全。为了防止采空区引发冒顶、片帮、地表下沉等灾害事故,通过对采空区分布、规模、稳定性等情况进行全面摸查,采用尾砂胶结充填以及封堵、隔离相结合的方案,并在地表设置监测点,最终完成采空区隐患治理,保护矿体地表小溪河床及乡村公路,有效遏制由采空区隐患导致的重特大安全事故发生,确保矿山正常安全生产。A fluorite mine with small scale are produced for many years,due to the scattered distribution of underground goaf,some geological data of the old goaf are lacked,which resulted to the distribution information of the goaf are not mastered by the engineering technicians of the mine,the safety production of the mine is influenced seriously. In order to prevent the disasters of roof caving,wall caving and surface subsidence cased by the goaf,based on the investigation of distribution,scale and stability of the goaf,the tailings consolidation filling scheme combined with sealing and isolating method is adopted,through setting monitoring points in the surface of the mining area,so as to deal with the goaf hidden trouble. The study results show that the governance scheme proposed in this paper is help for protect surface stream bed upon the ore-bodies and rural roads,besides that,major safety accidents caused by goaf can be cancelled effectively,and the safety production of the mine can be guaranteed.
