本文从安全及经济角度考虑，针对二次爆破一次点火的雷管数目较多经常发生超点现象，利用导爆索又浪费成本的实际情况，将火雷管改为非电导爆雷管。

Considering from safety and economy , the fire detonator is changed to non-electric blasting fuse detonator . The former is not safe and waste cost for using blasting fuse .

二是底排药剂的二次点火距离散布不影响总距离散布。

The range dispersion caused by dispersion of second ignition time does not affect the overall range dispersion of the shots .
