Bench blasting is the most usual type of blasting work . 梯段爆破是最常用的爆破工程之一。
The basic charge calculations have been concentrated round bench blasting . 装药计算的重点主要放在梯段爆破上。
Stopping can very well be compared with bench blasting but requires considerably larger charges . 崩落则十分相似于梯段爆破,只不过所需的装药量比较大一些。
Discussion on decreasing twice blasting for bench blasting 关于减少梯段爆破二次爆破量的探讨
