目前,尚没有一种十分准确的装药量的计算方法因为岩石构造、炸药性能、炮眼长度、最小抵抗线及自由面等客观条件都有很大的影响,同时,在装填技术上也是复杂的。在实际应用上,一般采用下列四种方法:(一)拉赖斯公式;(二)赫查(Haser)公式;(三)根据炮眼长度计算装药量;(四)根据药径大小计算装药量。这些方法都是各有优缺点的。根据我个人在实际应用时的体会,提出两
At present, there is not a very accurate method for calculating the amount of charge because of rock construction, explosive performance, bore length, minimum resistance line and free surface and other objective conditions have a great impact, at the same time, filling technology is also complex . In practical application, the following four methods are generally adopted: (1) La Rueis formula; (2) Haser formula; (3) Calculation of charge according to the length of blasthole; Dosage. Each of these methods has its advantages and disadvantages. According to my personal experience in practice, put forward two
