摘要
本文论述了井下发生沼气爆炸时空气冲击波的发生发展过程,以及空气冲击波沿井巷传播的衰减规律。并通过瓦斯爆炸试验和回归分析,得出了井下一定量的沼气在无煤尘参与的条件下发生爆炸时的安全距离。这一安全距离可供修订《煤矿救护规程》和处理事故时参考。
This paper deals with the occurence and development of the air shock wave induced by mine gas explosion. The attenuation law of the air shock wave during its propagation along drifts has also been discussed. On the basis of gas explosion tests (without taking part in of coal dust) in different gas content circumstances and regression analysis a series of safety distances have been obtained . It is helpful for drawing up the 'Rescue Regulation of Coal Mine'.
