露天边帮下紧邻尾矿库采空区地表充填治理方法

针对采空区废石充填常规处理方法难度大、费用高、安全性差等问题，结合排山楼金矿条件，研究了控制诱导冒落协同地表充填塌陷坑的采空区充填治理方法，包括采用RG井下电视监测评估空区冒落进程，从地表钻井充填保护露天坑尾矿库，崩落矿柱诱导空区冒透地表，地表充填塌陷坑恢复地貌，客土造田与恢复地表使用功能等方法.该方法用于排山楼金矿，使大型活动空区得到安全高效充填治理，取得了良好的技术经济效果.理论分析与实践表明，露天边帮下紧邻尾矿库的倾斜矿体采空区控制诱导冒落协同地表充填的治理方法，可减小采空区废石充填治理的难度，实现大型采空区安全高效治理.

Mined-Out Area Treatment Method by Surface Filling Under Open-Pit Slope Adjacent to Tailing Reservoir

Aimed at solving high cost， poor safety and extreme difficulty caused by conventional mined-out area treatment by waste rock filling， innovative mined-out area treatment method was studied by inducing and controlling caving as well as surface collapse pit filling， used in Paishanlou gold mine. The innovative methods including using of RG underground television monitoring and evaluation on mined-out area caving process， drilling from the surface protecting the open pit tailings reservoir， blasting ore pillar and inducing the emit through earth′s surface， recovering landform by filling collapse pit from the surface and land forming by alien earth and recovery surface function. The application of this innovative method in Paishanlou gold mine enables safe and efficient filling treatment of large-scale active mined-out area， and achieve good economical and technical results. Both theoretical analysis and practice shows that， for open-pit slope adjacent to the tailings reservoir of inclined ore body mined-out area， using controlled induced caving and surface filling method will reduce the difficulty of mined-out area waste rock filling treatment， and ensured safe and efficient treatment of large-scale mined-out area.
