一、群药包爆破的抛掷和堆积目前关于爆堆的计算,一般采用两种处理方法,即弹道理论法和体积平衡法。但是,由于对爆破抛掷规律认识的局限性,均未给出良好的计算结果。弹道理论法是在苏联学者影响下,以选取爆破漏斗内的微分单元体作为弹道抛掷计算微团,它不仅在数值计算上极其繁杂,同时也把握不住爆体运动的整体规律, First, the group of drug bag blasting throwing and accumulation At present, the calculation of the blasting pile, the general use of two treatment methods, namely the ballistic theory and volume balance method. However, no good results have been obtained due to the limitations of the knowledge of the law of blasting and throwing. The ballistic theory method is based on the influence of the Soviet scholar to select the differential unit in the blasting funnel as the trajectory to calculate the micro-ballistic throwing. It not only is extremely complicated in numerical calculation, but also can not hold the whole law of explosion movement,
