摘要(Abstract):
本文介绍水压爆破在露天矿的试验研究情况。根据水压爆破与普通瀑破对比试验的结果表明,水压爆破的降振率平均达到了31.3%,单孔装药量平均减少了37.0%,爆破效果比普通爆破好。
The experimental study on blasting with water pressure in openpit mine is described in this paper.The results from the comparison test be-tween blasting with water pressure and ordinary blasting showed that the ave-rage reduction rate of vibratiol1 of blasting with water pressure is 31·3%,the weight of charge per hole is reduced by 37%and blasting effect is alsobetter than those of ordinary blasting.
