软弱岩层巷道光面爆破参数的计算分析

Calculation and Analyses about Smooth Blasting Parameters of Incompetent Bed Roadway

根据软岩巷道光面爆破的原则及光爆机理,对光面爆破的不偶合指数、药卷直径、光爆周边眼距、炮孔深度、装药量、爆破方式等进行了分析,通过理论推导给出光爆参数的计算办法,并同时给出经验参考取值范围,以便相比较选最佳值,最后提出几个需说明的问题。

According to smooth blasting principles and smooth blasting mechanism of incompetent bed roadway, decouple index, cartridge diameter , peripheral hole spacing, hole depth, powered charge and blasting type of smooth , and so on, have been analyzed here. Calculation method of smooth blasting has been given by theoretically deducing; meanwhile, empirical preference taking value range has been given too, so as to compare each other to select optimum value. At the end, several problems that need illustrating have been given.
