摘要
通过对现场台阶爆破的高速摄影监测及爆堆的测量,分析了填塞物的逸出过程,给出了不同炮孔填塞高度和爆炸气体在孔内的作用时间;探讨了台阶爆破的爆堆伸出规律,对进一步研究台阶爆破参数的合理选择具有重要意义。
The process of the fill matter escaping in the bench explosion is analysed with the high-speed photography method .The relation between the height of the fill matter and action time of the gas has been given. The explosion pile extension regularity of the bench explosion is approached. The obtained results are important to researching the explosive parameter of bench.
