【摘要】 应用激波理论分析了底部空气柱装药爆破机理。通过实验室的爆破漏斗试验，研究了底部空气柱装药爆破效果，掌握了定量装药在固定装药深度情况下爆破漏斗体积与底部空气柱长度的变化规律，对工程实践有一定指导意义。更多还原

【Abstract】 he blasting mechanism of bottom air column charge is analysed with shock wave theory and its blasting effect is investigated through a series of crater tests on the cement mortar models. The law that the volume of crater varies with the length of bottom air column is obtained when the charge is located at a fixed depth in borehole.Valuable reference is offered for the engineering.更多还原
