| 摘 要： | 台阶式爆破主要针对大断面掘进巷道而使用的爆破工艺,可以很好地解决大药量同时起爆产生的强冲击波致使巷道成型变差以及瓦斯释放量的增加的问题;通过实践对比,台阶式爆破很好地解决了超挖和欠挖的现象,提高了爆破效果和巷道成型质量,降低了围岩和瓦斯的危害。

| Abstract: | Bench blasting is a blasting technique mainly applied in big cross section excavation road-ways ,and can effectively solve the problem of worse roadway formation and increase of gas emission caused by strong shock wave when a large amount of explosion blast at the same time .It is proved by practice that bench blasting can successively solve the problem of over and under excavation ,improve blas-ting effect and roadway formation quality ,and decrease the damage of surrounding rock and gas . |
