拆除爆破中雷管延时精度对破碎介质飞散的影响

EFFECT OF DETONATOR DELAY ACCURACY ON FRAGMENT FLYING IN DEMOLITION BLASTING

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。

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.
