露天深孔爆破药量计算与审查的问题,是我们矿山生产中经常碰到的问题。传统的露天深孔爆破药量计算公式是应用底盘抵抗线进行药量计算的。作者在爆破实践中发现,用传统的药量计算公式计算的药量往往偏高,有的甚至过高。作者在爆破实践中,采用平均抵抗线进行露天深孔药量计算,平均抵抗线是指炮孔剖面梯形的中位线,实践证明,用平均抵抗线计算的药量比较切合实
Open-hole deep hole blasting dose calculation and review of the problem is that we often encounter problems in mine production. Traditional open-hole deep-hole blasting dosage formula is the application of chassis resistance line dose calculation. In blasting practice, the author found that the dosage calculated by the traditional formula of dose calculation tends to be high, and some are even too high. In blasting practice, the average resistance line is used to calculate the open-hole deep hole dosage. The average resistance line refers to the median line of the trapezoid of the borehole cross section. Practice has proved that the dose calculated by the average resistance line is more realistic
