季节性冻土爆破参数试验研究

根据利文斯顿爆破漏斗理论,在黑山露天煤矿季节性冻土的松动爆破开挖现场,经过不同冻土条件下多种爆破方法的参数对比试验与效果分析,归纳了相应的钻孔直径、孔网参数、单位耗药量的优化数据,对季节性冻土爆破工程具有一定的参考价值。

The research on seasonally frozen ground blasting parameter test

According to Livingston blasting crater theory, through a large number of trials which took the blasting and excavation of seasonally frozen ground in Heishan strip mine as the background. On the basis of the parameters contrast test and effect analysis under multifarious blasting method of different permafrost conditions, the optimum data were given in terms of diameter of drilling hole, hole net parameters, unit explosive consumption, has the reference value for the seasonally frozen blasting project.
