摘要
本文结合柱状装药的爆破特性,分析探讨了单自面下垂直炮孔柱状装药微差爆破的破岩作用,并由此证明了深孔柱状装药采用孔内微差起爆将能够提高破岩深度,改善破岩质量。
In the light of the columnar blasting properties, preliminary investigations are conducted into the fragmentation of the columnar hole millisecond delay-action blasting in the single face. A conclusion is drawn that deep-hole columnar millisecond delay -action blasting can improve fragmentary depth and quality.
