The explosive cutting effect of shaped charge in the stone have been simulated by the experiments of cutting in the cement models mostly with powdery emulsion explosive ( PEE). The influence on powdery emulsion explosive property by adding inertial substance is investigated. 本文以粉状乳化炸药(PEE)为原料,通过对聚能效应在水泥砂浆试块模型中切割情况的研究,模拟了聚能装药在石材切割中的爆炸作用效果。
