深孔爆破技术在煤矿中的应用

Application of deep hole blasting technology in coal mine

针对煤矿在采用深孔爆破时确定爆破参数大多是只靠经验,没有进行定量的计算和分析的问题,通过理论分析深孔爆破中爆破参数的确定机理,得出了炮孔的布置方式、炮孔直径、炮孔间距、炮孔排距、不耦合系数、炮孔长度、封孔长度和一次起爆药量等这些爆破参数的确定方法,并通过示例说明这些参数的确定方法的正确性。

In view of the problem of the blast parameters determination, mostly only depending on the experience without quantitative calculation and analysis, through theoretical analysis of the blasting parameters determination mechanism, the blasting parameters determination method is obtained. The blast parameters include blast hole pattern, blast hole diameter, blast hole space, blast hole, decouple coefficient, blast hole length, plugging length and the explosive of ignition and so on. Finally these parameters are proved to be correct by examples.
