巷道连接形式对瓦斯爆炸的影响

Influence of Roadway Connection Form on Gas Explosion

通过对瓦斯爆炸规律进行整理分析,利用气体爆炸仿真模拟软件FLAC3D对瓦斯爆炸进行数值模拟,基于瓦斯爆炸机理,分别从巷道分岔、转弯等不同连接形式对瓦斯爆炸的影响等方面进行研究。结果表明:瓦斯在爆炸后,无论巷道采用何种连接方式,只要巷道发生分叉,爆炸过程对分岔点后各巷道的破坏程度,均比其对分叉点前主巷道的破坏程度严重。

Based on the law of the gas explosion and analyzed using gas explosion simulation software FLAC3D for numerical simulation of gas explosion, gas explosion mechanism, respectively, based on bifurcation from the roadway, cornering and other forms of different connections on the impact of gas explosion in areas such as research. The results showed that: gas after the explosion, no matter in what connection the roadway, as long as the roadway occurred bifurcation, bifurcation point explosion on the extent of the damage after the roadway bifurcation point than on the extent of damage before the main roadway serious.
