摘要
针对大部分水泥矿山爆破使用连续装药结构存在的问题,在钱家山矿山采用空气间隔装药结构进行爆破实践,降低了大块率及单耗,充分利用了炸药能量,并降低了爆破震动,取得良好的预期效果,改善了爆破质量。
Airning at the problem of continuous charging structure in most cement mine blasting, air-deck charging structure was practiced in Qianjiashan mine. It reduced boulder yield and unit explosive consumption, took full advan- tage of explosive energy, and reduced blasting vibration. It got good desired effect, improved blasting quality.
