摘要
本文介绍了复杂条件下残矿回收的方法。分布于空区充填体中的散体残矿采用超前注浆固结、构造矿房回采方法加以利用;对多分段难采矿柱群残留矿,利用大直径深孔整体崩落法进行回收;对于分散难采的铜、铀等矿,可以用就地堆浸的方式回收残留矿石。
This paper introduces several recovering methods of residual ore. Room mining technology can be used to recover the residual ore distributing in backfill, and that pre-grouting is necessary for good working conditions. For the multi- stages refractory pillars in bad conditions, mass caving with bundle-hole is adoptable. In-pLace leaching can be used to recover scattered ,low-grade ore in copper and uriuam mine.
