偏心不耦合装药爆破参数理论分析

Theoretical Analysis on the Parameters of Eccentric Decouple Charge Blasting

在边坡开挖工程中,光面(预裂)爆破常常都采用偏心不耦合装药结构。提出了一种表征偏心不耦合装药爆破时,计算不同点孔壁压力的一个重要参数,即点不耦合系数。在此基础上,计算了孔壁各点压力,分析了偏心装药爆破时合理的点不耦合系数的取值。研究结果对于指导光面爆破参数选取有一定的参考价值。

Eccentric decouple charge is applied to smooth blasting in slope evaluation engineering. Decouple coefficient of point is given in this paper. It is an important parameter of calculating pressure of different point on bore wall for eccentric decouple charge blasting. On the basis of it, pressure of different point on bore wall is calculated and reasonable decouple coefficient value of point is analyzed. The testing results can provide reference for parame- ters selection of smooth blasting.
