摘 要:通过对河台金矿高村矿床所形成数十万m3的采空区调查 ,分析其破坏原因及危害范围 ,并提出以各种人工矿柱或低品位矿石矿柱支撑空区 ,变大空区为各自独立的小空区 ,与用自然片落形成废石垫层的处理方法 ,不但可保证安全生产 。The investigation of several hundreds thousands m 3 of mined out area of Gaocun Gold Deposit of Hetai Gold Mine was made,and the reason of its destruction and scope of harm were analysed.On these basis,this paper proposed to support the mined out area by diverse artifcial ore pillars and low grade ore pillars,by way of changing big mined out area into small independent mined out areas and by dividing natural part into waste rock padded stratum.As a result,not only the safety operation was guaranteed but the economic benefit emerged.
