深井卸荷开采技术研究

Study on Unloaded Mining Technology for Deep Mine

针对深井开采的技术难题,结合凡口铅锌矿的具体条件,对4种卸荷开采方式进行了分析比较,确定了两端立槽卸荷方案。在此基础上,深入分析了卸荷立槽规模和整体开采顺序对卸荷效果的影响,提出了经济合理的卸荷方案和整体推进的开采顺序。

In view of the technical problems in deep mining, in combination of the specific conditions in Fankou lead - zinc mine, the authors analyzed 4 kinds of unloaded mining methods and determined the plan of unloading by vertically cuts at two ends. On the basis of this, the effects of size of vertical unloading cuts and overall mining sequence on the results of unloading were deeply analyzed, an economic and reasonable unloading plan and the overall advancing sequence for mining were put forward.
