摘　　要：璜山金矿所在区域断裂构造发育,顶底板围岩条件较差,采矿损失率、贫化率较高,还存在诸多安全、环境问题。为此矿山采用充填法进行实践,基于矿山开采技术条件、现有充填系统、深部应力环境,设计采场的长度50 m、阶段高度30~40 m,标准矿块的综合回采率为93.5%,综合损失率6.5%,采矿贫化率控制在5%以内,取得了较好的实践效果。Huangshan gold mine is located in the area of fracture tectonic development,the top and bottom plate peripheral rock conditions are poor,mining loss rate,depletion rate is high,there are also many safety and environmental problems.For this reason,the mine adopts the filling method to practice,based on the technical conditions of mining,the existing filling system,the deep stress environment,the design of the length of the quarry 50 m,the design of the height of the stage is 30~40 m,the standard ore block of the integrated recovery rate of 93.5%,the integrated loss rate of 6.5%,the rate of mining depletion is controlled at 5%or less,and has achieved a better practical effect,and for similar mines to carry out the filling method mining practice and research has a certain reference significance.
