基于焦耳定律对丢炮落炮现象的研究分析

Study and Analysis on Blasting Lost and Blasting Fallen Phenomenon Based on Joule law

矿山串联爆破作业中,时常出现丢炮、落炮现象,是矿山采掘作业中的重大安全隐患。基于焦耳定律,对影响爆破网路爆破效果的三大因素——电流、电阻和时间进行了分析,对丢炮、落炮原因进行了剖析,并提出了应对办法。即具体问题具体分析,查明原因,采取措施,消除丢炮、落炮隐患,实现安全放炮。

In the mine series blasting operation,a blasting lost and blasting fallen phenomenon often occurred and would be an important potential safety danger in the mine mining and excavation operation.Based on the Joule law,an analysis was conducted on the three factors of the current,resistance and time affected to the blasting effect of the blasting network,an analysis was conducted on the blasting lost and blasting fallen causes and the countermeasures were provided.The safety blasting could be realized on the certain problems with the certainly analysis,the causes clarified,measures conducted,elimination on the blasting lost and blasting fallen potential danger.
