摘　　要：分析了三山岛金矿深部采场充填存在的问题,提出采用分次充填、分区充填、多点下料及强制充填等方法解决充填接顶率低的问题。根据理论计算,对深部矿区一步采采场及二步采采场支护设计参数进行优化,以确保采场回采安全。The problem existing in the filling operation of deep stope in Sanshandao gold mine was analyzed.Some means such as stage filling,divisional filling,multi-point filling and forced filling were proposed to solve the problem of low roof-contacted filling rate.Based on the theoretical calculation,the design parameters of support for first step stope and second step stope were optimized so as to ensure the safety of stoping.
