摘要
某锡矿山前期采用有底柱分段空场法回采矿体,留下大量底柱资源未开采。为了安全、高效地回收资源,通过优选比较"有底柱中深孔崩落法"和"无底柱中深孔崩落法"两种采矿方案,最终选取"有底柱中深孔崩落法"回采上中段留下的底柱及下部矿体。"有底柱中深孔崩落法"能够安全回收该区域内的残矿资源,创造了良好的经济效益。
A mine used sublevel open stoping method to exploit orebody, which is leaving a large number of bottom pillar. By comparing＂ deep hole caving method with bottom column＂ and＂ deep hole caving method＂ two mining methods, it finally selects＂ deep hole caving method with pillar＂ to stope bottom column in the abutment and the lower part of ore body. ＂deep hole caving method with bottom column＂ is useful to explored this kind of ore, which creats a good economic benefit.
