摘要(Abstract):

就新、旧两类不同炮孔堵塞材料所形成的炮孔堵塞体的抗滑和抗剪能力、在炮孔中的运动形式、传递爆炸气体压力的作用以及所吸收的爆炸能量等几个方面进行初步比较,以此说明新炮孔堵塞材料的堵塞能力和堵塞效果.
The paper made a primary comparison between the stemming bodies formed bynew and old materials in the resistance to slipping and to shear, the moving formations inblastholes, the function of transferring the gas pressure from explosion and the absorbed explosion energy, then explaining the plugging ability and effect of the new stemming material.
