摘要
对石灰石露天矿山台阶深孔凿岩爆破中大块产生原因进行了分析,并从穿孔参数、炸药单耗、装药结构、微差间隔、起爆方式等方面,提出降低大块率的技术措施,在实践中取得较好的爆破效果。
Based on the analysis of causes on which the blasting boulder occurs in borehole blasting of the limestone open pit, the pa per determined some measures of lowering boulder yield of borehole blasting operation in the limestone mining open pits by borehole parameters, taking explosive specific charge, charge structure, millisecond interval and detonating into design of blasting program. The blasting with the controlling measures resulted in very satisfied effects in practice.
