两种起爆方法在七宝山矿的应用比较

Comparison of Using Two Detonating Methods at Qibaoshan Iron Mine

通过采用导爆索起爆法和非电导爆管起爆法两次深孔爆破试验,并对这两种爆破方法的技术经济指标和优缺点进行比较,得出非电导爆管起爆法无论在技术经济指标方面,还是在爆破效果方面均比导爆索起爆法优越的结论。试验结果为非电导爆管起爆法在七宝山铁矿的全面推广奠定了基础。

Through blasting tests of fuse initiating and non-electric detonating tube initiating method,the advantages and disadvantages of two methods and technico economical indexes are analysed. Whether technico economical indexes or blasting effect non-electric detonating tube initiating method is better than fuse initiating method. The result shows that non-electric detonating tube initiating method has base in overall popularization at Qibaoshan iron mine.
