本文简要介绍了M.H.科萨切夫等研究人员在研究挤压程度时装药量影响问题时确定挤压指标的方法。作者认为,利用这些挤压指标难以确定挤压系数。作者等人的研究证实,挤压作用对爆破效果的影响取决于介质中药包相对于自由面的空间位置。并提出了计算集中药包及加长药包挤压系数的公式。 This article gives a brief introduction of the methods used by researchers such as M.H. Kosakhev and others to determine the squeeze index when investigating the effects of loading on extrusion. The author believes that the use of these extrusion indicators is difficult to determine the extrusion coefficient. The study by the author et al. Confirmed that the effect of extrusion on the blasting effect depends on the spatial position of the drug pack relative to the free surface. The formulas for calculating the concentration of drug packets and extending the extrusion coefficient of drug packets are also proposed.
