【摘要】 在对原始缓边坡进行整形爆破处理的过程中,采用常规的深孔爆破方法易出现根底和大块。文章以乌龙泉矿西区原始缓边坡为例,从理论上分析了出现这一问题的原因,提出采用大直径孔药壶爆破可较好地处理这一问题。通过现场工业试验,分析药壶爆破效果,证实它在技术上是可行的,并在试验的基础上,比较分析其技术经济指标,得出大直径孔药壶爆破在经济上也是合理的。更多还原

【Abstract】 During the shaping blasting in primal gentle slope,the toe rocks and boulders are produced readily in general deep-hole blasting.Taking the west area in Wulongquan Limestone Mine of WISCO as an example,the reason is analyzed and large diameter deep-hole springing blasting is suggested.Through the industrial test and analyzing the results,this method is successful in practice.Comparing their technical and economical index,the springing blasting is reasonable in economy too.更多还原
