摘要(Abstract):

分析了雷管延时精度对最小抵抗线及破碎介质飞散速度的影响,在此基础上提出允许延时误差的计算方法及减少误差对介质飞散影响的几点措施
In this paper, the effect of detonator delay accuracy on burden and fragment flying velocity was analyzed. The method of calculating the allowable delayed error and the measures of reducing the effect of low accuracy on fragment flying were put forward based on the above.

关键词(KeyWords): 拆除爆破;延时精度;飞散速度
