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。
介紹瞭遂昌金礦迴收淺孔留礦採場空區內遺留的礦石頂、底柱，嗣後採用掘進廢石榦式充填採空區等處理措施，併藉助充填體作為鑿巖、齣礦等作業平檯，利用二次應力測試(光應力計)等鑑測手段，安全迴收頂、底柱殘礦，消除瞭安全隱患的同時，減少瞭地錶廢石堆放麵積。穫得一定的經濟和社會效益。

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.
