在评价露天爆破效果及爆破优化的研究中,爆岩块度的测量及块度的定量描述是首先必须解决的基本问题。用生产爆破试验来研究上述问题,需要消耗大量人力、物力,而且进行起来是很困难。用小台阶爆破试验来代替生产规模的试验是经济与可行的。为此,我们在内 In the research of blasting effect and blasting optimization, the measurement of rock burst and the quantitative description of rock block are the basic problems to be solved first. The production of blasting test to study the above problems, the need to consume a lot of manpower and material resources, and to carry out it is very difficult. It is economical and feasible to replace the production scale test with a small bench blasting test. For this reason, we are included
