采石场条形药包硐室爆破

在复杂地质、地形及周围环境条件下,采用分段间隔堵塞、同药巷内分段毫秒延时爆破的条形药包硐室爆破技术,针对不同地形的条件和不同的爆堆堆积范围,采用不同的W值等爆破参数,完成采石场硐室爆破工程。爆破效果较好,达到了工程要求。

STRIP CHARGE CHAMBER BLASTING IN QUARRY

A strip charge chamber blasting engineering carried out in a quarry under the complicated geological,topographical and surrounding was presented.In the engineering the interval blocking,delay millisecond blasting in one charging lane,various blasting parameters like W value in accordance with topography and accumulating scope of different blasting pile,were employed.The blasting satisfied the requirement of the engineering,and good blasting effect was reached.
