炮孔堵塞物运动规律的理论探讨

Ivestigation into Move Regulavity about Stemmed Material in Hole Charge Blasting

本文分析了炮孔装药爆破时炮孔堵塞物的受力情况，建立了爆生气体作用下堵塞物的运动方程。并根据动量守恒和能量守恒，求算出了堵塞物的初始运动速度和脱离孔口时的速度．

Forces about stemmed material are analysed in hole Charge. Stemmed material move equation in hole is established on the explosion gas .On the basis of laws of Conservation of momentum and energy, initial velocity and hole-head-velocity about Stamened material are Calculated.
