摘　　要：针对随开采形成的地下空区给矿山及周边带来安全隐患等问题 ,将地下空区改建成尾矿库是今后矿业开发的一个发展方向。分析和研究了改建过程中的空区稳定性、尾矿输送下料、尾矿水排放与回收、井下封闭挡墙、尾矿渗漏与封堵等关键技术问题。The underground vacant formed during mining can bring hidden danger to the safety of both the mine and surrounding area. It will be a trend for the future mining development to transform the underground mined area into tailings reservoir. Key technical issues concerning the transformation such as the stability of mined area, tailings transportation and discharging, the drainage and recycling of the tailings water, underground retaining wall, tailings leakage and sealing are analyzed and studied.
