摘要
某铅锌矿采矿方法存在一定的安全隐患,且效率低下,针对以上存在的问题,该文向矿山推荐了"分段凿岩阶段出矿两步骤回采嗣后充填法"及"分段凿岩阶段出矿嗣后充填法"2种采矿方案,并对其主要技术经济指标进行了分析比较。以安全性及可比经济效益好为原则,最终确定以"分段凿岩阶段出矿两步骤回采嗣后充填法"作为矿山的主要采矿方法,其在后期矿山生产实践中也得到了合理验证。
Some hidden dangers and low efficiency exist for the mining method of a lead-zinc mine.In view of the problems above,this paper recommends two mining schemes including"the vertical strike of sub-drilling with two-step stoping stage extracting ore of delayed backfilling method"and"the vertical strike of sub-drilling with stage extracting ore of delayed backfilling mining method".Then the main technical and economic indexes of the mining methods are analyzed.On the principle of safety and better economic benefits,the"the vertical strike of sub-drilling with two-step stoping stage extracting ore of delayed backfilling method"is finally determined as the main mining method in the mine,and it has also been verified in later production practice of the mine.
