摘要
本文运用数学工具——应用概率统计中的方差分析,对光面爆破中出现的超、欠挖问题进行了具体的、数值上的计算分析,针对影响光爆效果的各种因素,结合日本专家吉见宪一采用现场实验的方法得到的结果,即在周边孔间距E,最小抵抗线W和装药集中度P三因素中,影响光爆效果的重要因素是装药集中度的大小。最后得出了减少超挖、提高光爆效果的结论。
The numerical analysis of over-and underexcavation by smooth surface blasting were carried out by root ean square deviationin probablity statistics. With regards to factors influencing effects ofsmooth surface blasting in ombination with results form field test, thatis, among three factors, namely, spacing between peripherical holes E,minimum resistance line W and degree of charge concentration P, the Pis the most important.
