炮孔直径与装药直径的比值称为装药不耦合系数.
且随着装药不耦合系数值增大，孔壁压力降低，空气不耦合装药时孔壁压力下降速率更快。
With the coefficient of uncouple charge increasing, pressure of bore wall descended. The rate of pressure of bore wall decreased fastest when air-uncouple charge condition.
鉴于以上结论，进一步分析了上部空气层装药结构轴向不耦合系数与起爆方式对爆破效果的影响。
Based on these conclusions, the influence of axial decoupling coefficient of top-air-decked charge structure and detonating manner on blasting effect is analyzed here.
通过大量的预裂爆破试验，得出了适用于该边坡的炮孔直径、炮孔间距、线装药密度、不耦合系数等一系列常规预裂爆破参数。
Pre-splitting blasting experiments were carried out to obtain normal pre-splitting blasting parameters such as hole diameter, hole space, gun- powder charge line density, and uncoupling factor.
