摘  要:介绍了遂昌金矿回收浅孔留矿采场空区内遗留的矿石顶、底柱,嗣后采用掘进废石干式充填采空区等处理措施,并借助充填体作为凿岩、出矿等作业平台,利用二次应力测试(光应力计)等监测手段,安全回收顶、底柱残矿,消除了安全隐患的同时,减少了地表废石堆放面积。获得一定的经济和社会效益。The residual roof and bottom pillars in mined-out area of shallow-hole shrinkage stope are retrieved,then the treatment measures that dry waste rocks from drilling are filled into the mined-out area are adopted in Suichang Gold Mine. With the aid of the filling body used as drilling,ore removal and other working platforms,the monitoring measure like secondary stress test( photoelastic stressmeter) is applied to retrieve the residual roof and bottom pillars safely. It eliminated the potential hazard in safety,and reduced the accumulation of waste rocks. Hence,a certain social and economic benefit was obtained.
