摘要
分析了老龄露天矿山的边坡和边坡施工中存在的问题,通过对爆破过程中矿岩破碎原理的分析,在实践中确定了适合露天大孔径深孔爆破条件的预裂爆破参数。
The problems in slope and its construction of old surface mine are analyzed, the presplitting blasting parameters suitable for large - diameter deep hole of surface mine are determined in practice based upon the analysis of mine rock breaking principle.
