障碍物影响下瓦斯爆炸压力传播规律研究

Study on Propagation Rule of Gas Explosion Under the Conditions of Barrier

我国煤矿事故频发,尤其瓦斯爆炸事故,给国家和人民的生命财产造成巨大损失。对瓦斯在障碍物条件下的爆炸压力传播规律进行研究,对预防和减小煤矿巷道内的瓦斯爆炸危害具有重要意义。本文利用水平管道式气体爆炸测试装置,研究了障碍物对瓦斯爆炸压力的传播规律影响,得出障碍物的存在对瓦斯爆炸压力具有激励作用,加大了瓦斯的爆炸威力。

In China,coal mine accidents frequently. Especially,gas explosion causes huge losses to the state and people s lives and property. So,to study the pressure and propagation of gas explosion under the conditions of barrier is very significance for preventing and reducing the hazard of gas explosion in coal mines. In this paper,the author mainly studies the effect of barrier in the horizontal pipeline. The existence of barriers is a motivation to gas explosion pressure,increasing the power of a gas explosive.
