几种水下钻孔爆破炸药单耗计算公式的分析与比较

摘要

There is a big difference of specific charge between underwater blasting and blasting in open-pit mine. The factors influencing on the specific charge of underwater drilling blasting was analyzed,and the several calculation formulas of domestic and overseas were also analyzed and compared. At last, the revised method of specific charge calculation of underwater blasting was proposed based on the slag cleaning device.%水下爆破需要的炸药单耗与露天爆破相比存在很大差异.分析了水下钻孔爆破单耗的影响因素,对国内外的几种计算公式进行了分析比较,提出了基于清渣设备能力的水下爆破炸药单耗计算的修正方法.
