摘要

针对某钨矿山采用浅孔留矿法采矿时贫化率大的问题,提出了动态圈定采幅、优化回采技术方案、制定"优质优价"技术管理等控制措施,并应用于矿区生产实践。结果表明,贫化控制措施取得了良好的效果,使年平均贫化率下降了5.8%,降低了直接生产成本,增强了企业的市场竞争力。
        Aiming at the problem of high dilution rate when using shallow hole shrinkage mining method, several control measures, such as dynamic delineation of mining area, optimized mining technical scheme and technical management of high quality & better price, are put forward and applied to production practice. The result shows that, the dilution control measures have achieved good benefits, reducing the annual average dilution rate by 5.8%, Which also cut down production cost and enhance market competition ability.
