低爆速炸药破碎混凝土块的试验

用低爆速炸药与乳化炸药对两种尺寸的混凝土块进行了爆破实验,并对破碎效果进行了比较。结果表明,低爆速炸药的猛度和爆力都明显小于乳化炸药。这印证了低爆速炸药所具备的低猛度、低爆力的性能特点,有利于在复杂环境中用于爆破拆除基础等构筑物。

AN EXPERIMENT ON FRAGMENTATION OF CONCRETE BLOCKS BY LOW-VELOCITY EXPLOSIVE

A blasting experiment was conducted on fragmentation of the concrete blocks with two dimensions by low velocity explosive and emulsion explosive and the comparison between fragmentation results was doneThe comparison result shows that the brisance and detonation power of low velocity explosive are remarkably less than that of emulsion explosiveThis experiment confirms that low velocity explosive is characterized by low brisance and detonation powerIt is favorable for blasting demolition of such structures as a concrete foundation under complex condition
