摘要
充填采矿法从最初的以处理废石为目的发展到后来改善采场稳定性,该方法在现代采矿活动中占比越来越大。桦树沟铜矿使用全尾砂结构流胶结工艺,利用铜选矿尾砂作为充填骨料,解决采空区和尾矿库两大矿山危险源,防止地表塌陷及上部矿岩的稳定,而且还可充分利用地表固体废弃物,成为矿山安全、高效、环保的标志。
From the initial purpose of treating waste rock to the improvement of stope stability,backfill mining method has taken up an increasing proportion in modern mining activities.Huashugou copper mine USES the whole tailings structure flow cementing technology,USES the copper dressing tailings as the filling aggregate,solves the goaf and the tailings pond two mine dangerous sources,prevents the surface collapse and the upper ore rock stability,moreover may also make full use of the surface solid waste,becomes the mine safety,the highly effective,the environmental protection symbol.
