三道庄露天矿岩石爆破性分级试验研究

Study of the classification of rock blastability of the Sandaozhuang surface mine

基于岩石爆破性分级的合理判据 ,对预估炸药消耗、预报爆破块度和爆破参数的优化具有重要意义 ,本文采用“岩石爆破性指数”分级法 ,对三道庄露天矿岩石进行分级 。

The reasonable criterion of the classification of rock blastability is significant in evaluation of the consumption of explosive,the predication of blasted rock fragment and the optimization of blast parameter.This paper adopts classification method of ' rock blastability index' to classify the blastability of the rocks of Sandaozhuang surface mine.The obtained results more actually illustrate the blastability of the rocks of the mine.
