天然焦火成岩区域爆破安全保障技术的研究及实践

Research and practice on safety guarantee technology of blasting in natural coke igneous rock area

天然焦具有导电的物理特性,爆破时容易出现丢炮现象,在采煤工作面遇到天然焦火成岩区域,为了避免出现丢炮,保证爆破工作的安全,采取一系列安全保障技术措施,杜绝了丢炮,大幅提升爆破安全性,为采煤工作面高效推进提供安全保障。

Natural coke has the physical characteristics of conductivity,and it is easy to drop guns when blasting.In order to avoid dropping guns and ensure the safety of blasting work,a series of technical measures were adopted to prevent dropping guns,greatly improved the safety of blasting,to provide safety guarantee for efficient advance of coal mining face.
