摘要
在扼要分析了有底柱崩落采矿法 ,一次多排挤压爆破落矿存在问题的基础上 ,介绍了一种分块落矿的有底柱分块崩落采矿法 ,该方法与一次挤压落矿相比采切比可降低 1~ 2m ,,回收率提高 3 %~ 5 %。
Based on analysis of multi row a extrusion blast in caving with pillars,the paper presents the method of brock caving with pillars,which developing works will be reduced by 1~2m,the recovery will be increased by 3%~5%.
