摘　　要：针对浅孔留矿法开采漂塘矿区破碎矿体存在片帮、昌顶、放矿困难等回采安全问题,提出静态留矿法技术方案,并进行了工业试验。结果表明,在放矿口架设溜矿井,专用于局部放矿,使矿房内的大部分矿石保持静止,充当干式充填作用,同时避免矿石流动对上下盘围岩的摩擦、冲击和挤压,保持上下盘围岩的稳定性,为顺利回采创造条件。对该矿区而言,静态留矿法是一种安全有效的采矿方法。To address stoping safety problems such as wall caving, roof caving and difficult ore drawing brought by mining of Piaotang mine broken ore body with shallow-hole shrinkage method, static shrinkage method is proposed and put to commercial tests. The test results show that if ore chute specifically for local ore drawing is set up at draw hole, most of ores inside the chamber will remain still, having a dry filling function. Meanwhile, [riction, impact and squeezing on upper and lower wallrocks caused by flow of ores can be avoided and stability of upper and lower wallrocks can be ensured, which are conducive to successful stoping. For this mine, static shrinkage method is a safe and reliable mining method.
