摘要
贵州开磷集团用沙坝矿急倾斜破碎矿体属于难采矿体。根据该类矿体的赋存条件,通过对适用的6种采矿方案进行技术经济分析、比较,决定采用分段凿岩阶段空场嗣后充填采矿法。详细介绍了该采矿工艺的结构参数、采准工程、回采工艺及主要技术经济指标。
The steep incline and fractured ore-body in Yongshaba Mine of Guizhou Kinlin Group belongs to difficult-to-mine ore- body. For the sake of this, based on the occurrence of these orebody, six mining methods that can be used are analysed and compared with one another by technical economic analysis. Tile sublevel drilling open stoping in stage with subsequent filling process is decided to be adopted. The paper introduces detailedly the mining process including structure factors, development works and ex traction technology etc..
