Here is another approximation formula come from practice to determine the explosiveconsumption. It is more practical and could be calculated precisely without the table.
现通过实践，推导出单位炸药消耗量的近似计算公式，与查表求出的数值基本吻合，从而更具有实用性。

Under the condition of certain definite blasting parameters, it was found out that interval charging could reduce unit explosiveconsumption and also kept good broken effects.
在某些爆破参数确定的条件下，施工中摸索出空气间隔装药结构能降低炸药单耗，同时保证了破碎效果。

The traditional deep-hole blasting for tunnels USES pure clay to stem the blast-holes. The efficient energy availability of explosive is not high and the specific explosiveconsumption is large.
