摘要
从理论上分析了不同装药结构爆破时的孔壁初始冲击压力 .结果表明 :较坚硬致密的高阻抗岩石 ,孔壁冲击压力值较高 ,较松散软弱的低阻抗岩石 ,孔壁冲击压力值较低 .当岩石条件一定时 ,随着装药不耦合系数值增大 ,孔壁冲击压力降低 ,并且在空气不耦合装药时孔壁压力下降速率更快 .
Based on the theoretical analysis of the initial shock pressures of different charging constitutions on the borehole wall,the following conclusions are reached:that in the case of the densely compacted high impedient rock of high hardness,the shock pressure on the wall is great,and in the case of loosely compacted low impedient rock of low hardness,the shock pressure on the wall is less great;and that in the case of a rock of given conditions,the shock pressure on the wall varies inversely with the coefficient of decoupling charging,and this is remarkable in the air decoupling charging.
