Effect of Water-bath Heating on the Explosion Power of Emulsion Explosive
摘要： 为了研究高温炮孔对水浴防护下乳化炸药爆炸威力的影响,采用100 ℃水浴加热模拟高温炮孔中防护下乳化炸药的环境温度,通过水下爆炸实验计算得到水下爆炸参数.结果表明: 乳化炸药的爆速、冲击波冲量、比冲击波能、比气泡能以及总能量随着水浴加热时间的增加而下降,其中乳化炸药比气泡能与总能量随着水浴加热时间增加呈近似线性降低,水浴加热时间增加对比气泡能占总能量的比例变化影响较小,其比例保持在65%左右. Abstract： To study the effect of high temperature blast hole on the explosion power of water bath protected emulsion explosive, the enviroment temperature of protected emulsion explosive in high temperature blast hole were simulated by 100 ℃ water bath heating and the underwater explosion parameters were caculated and obtained through underwater explosion experiments.Results show that the detonation velocity, shock wave impulse, specific shock wave energy, specific bubble energy and total energy of emulsion explosive decrease with the increase of water bath heating time.In which, the specific bubble energy and total energy of emulsion explosive decrease in approximately linearly with the increase of water bath heating time, whereas, the effect of increase of water bath heating time on the proportion of specific bubble energy in total energy is smaller and the proportion remains at about 65%.
