平巷/坑道-钻孔地浸——一种需要重视的采矿方法

An Attractive Mining Method: In-situ Leaching of Borehole in Level/Gallery

平巷/坑道-钻孔地浸采矿方法是利用平巷/坑道开展钻孔地浸采矿的方法。20世纪70年代后,苏联不仅应用于其开采过一些砂岩型铀矿床,而且成功应用于开采陡产状的花岗岩型铀矿床,并进行残矿回收,具有较好的经济效益。该采矿方法在中国鲜有报道,文章介绍塔吉克斯坦境内金伊克-塔尔花岗岩型矿床坑道-钻孔地浸采矿有关情况,供研究该方法时参考。

In-situ leaching of borehole in level/Gallery is a method to in-situ leaching the ore by the drilling in the level/gallery. In 1970＇s, the former Soviet Union not only used this method to mine sandstone uranium deposit, but also succeeded in mining granite uranium deposit of steep attitude and recover the residual ore. This method is economic and seldom reported in China. In this paper, the In-situ leaching of borehole in level/Gallery in Kinierk-Tar granite uranium deposit was introduced as the reference for the method study.
