摘要
井下矿山二次破碎裸露爆破可采用聚能药包和水封聚能药包破碎大块．聚能药包能改变药柱某个方向的猛度，提高炸药能量利用率；水封爆破利用了炸药的猛度和一部分爆力作用，从而有效地利用了炸药本身的能量，降低了爆破危害．
The bare blasting for second fragmentation of underground mine can make use of shaped charges and water sealed shaped charges to fragment big ore black.The shaped charges can change a directional strength of explosive column and increaes the utilization factor of explosive.The water sealed blasting is utilization of strength of explosive and its partial blasting force,thus the energy of explosive can be effectively utilized and the blasting harm can be decreased.
