矿块采准工程兼探矿变级在白云金矿的实践

Practice of ore block preliminary mining design used as exploration gradation change

介绍了白云金矿省去小中段专用生探工程 ,直接在C级矿块上作采准设计。用矿块采准工程兼起探矿作用 ,便可获得储量变级和备采矿量变级 ,一步到位的双重效果 。

The preliminary mining of C ore block, used as exploration as well, is applied in Baiyun Gold Mine, obtaining the change of ore reserves and spare exploitation quantities, and bringing about remarkable economic benefits.
