光面爆破软垫层装药结构参数理论分析

以空气垫层和水垫层为例介绍软垫层光面爆破装药结构爆破机理，软垫层缓冲了爆炸压力，减少了对孔壁岩石的压缩破坏，延长了爆生气体液静压力的作用时间，有利于光爆成缝。据光面爆破要求，分析了软垫层光爆装药结构参数，主要探讨了轴向不耦合系数或软垫层高度的确定方法，提出理论计算公式。

Theoretical analysis on the parameters of smooth blasting soft mat layer charging construction

The blasting mechanism of smooth blasting soft mat layer charging construction (for example, air layer and layer) is introduced. The soft mat layer can not only cushion explosion gas pressure and reduce compress breaking on hole wall, but also extend action time of explosion gas pressure. In the light of smooth blasting, the parameters of smooth blasting soft mat layer (axial decoupling coefficient or the length of layer) are studied and theoretical calculating formulas are put forward.
