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。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.
