下向水平胶结充填采矿法在黄狮涝矿区的应用

摘要

对矿岩均为极破碎、稳定性极差、开采技术条件复杂的金矿床的开采,长期以来一直是采矿界的一个亟待解决的难题.铜冠黄狮涝金矿有限公司黄狮涝矿区多年来应用下向水平分层进路碎石胶结充填采矿法较好地解决了此难题,取得的主要技术指标为采场生产能力30～40 t/d,矿石贫化率4％ ～6％,矿石损失率5％ ～7％,采出矿石160万t.%Some rock is fractured,poorly stability and the mining technical condition is more complex. It is a complex problem in the China mining region. Huangshilao gold mine in Tongling Huangshilao Cold Mine Limited Liability Company adopted the downward drift slicing and filling with waste rock mining method,and this method overcome these problems. The main technical indicators are as follows,the production capacity of its stope is 30 ~ 40 t/d,ore dilution rate is 4% ~ 6% ,ore loss rate is 5% -7%. The production is 1 600 kt using the filling with waste rock mining method.
