摘要
以单孔爆破为例，研究柱装炸药爆破时产生的粉尘颗粒物和爆生气体的相对运动过程，分别在冲击运动阶段、蘑菇云形成阶段和扩散运动阶段对粉尘颗粒物进行受力分析，讨论爆破方式及水平风场对运动过程的影响，并在此基础上分别建立爆破粉尘在铅直方向。
A very important problem to be solved in openpit mines is preventing the blasting dust pollution. This paper studies the movement of blasting dust particles and gas, analyzes the force of dust particles in the impact movement of blasting, mushroom clouds movement and diffision movement, studies the effect of types of blasting and wind on each process. Itestablishes the momentum equation of dust particles on the basis of the studies in three directions: vertical direction, horizontal wind direction and horizontal crosswise wind direction.
