深孔掏槽抛碴的研究

The Initial Study of Fragment Discharge In Deep Holes

着重讨论深孔爆破初期破碎岩块又爆生气体混合物的运动，从数理统计及流体力学方面了进行了探讨。由于掏槽壁的摩擦作用，故将爆轰产物流当作粘性流处理。

The article discussed the movement of the mixture of scattering rock and blasting gases in theview of Statistics and Fluid Mechanics. For the friction of the wall of the cutting area, the movement of the blasting products should be treated as viscous fluid.
