上向分层充填采矿法在残采矿段的应用研究

The application of upward-slicing cut and fill stoping method in residual orebody

文章针对浅孔留矿法造成的残采矿段开采难题,分析了上向分层充填采矿法在该矿段的应用情况;分析结果表明,上向分层充填采矿法可以提高资源回收率63%,降低矿石贫化率10%,残采矿段采场顶板事故降低为0,但充填前期投入较大,受残采空区影响大,应进一步开发适合残采空区的充填技术。

In order to deal with the problems caused by the shallow-hole shrinkage method,this paper analyzes on the application of upward-slicing cut and fill stoping method in the mine;The results show that the method can improve 63% of the resource recovery, re- duce 10% of the ore dilution rate, and decrease the accidents of residual orebody into zero.But the early injection of filling is too larger, further development of the cut and fill method suiting for residual orebody is necessary.
