瓦斯在通风巷道中流动分布情况研究

瓦斯灾害是煤矿生产中的重要灾害，本文根据矿井通风理论以及图论基本原理，在得到矿井瓦斯涌出现规律的前提下，建立了计算瓦斯在煤矿井下巷道中运动时，瓦斯流量分布情况数学模型，并对该模型的数理性质进行了简要分析，得到该模型用于现场瓦斯治理的方法。最后，通过在现场实际验证，表明了文中所述方法对于现场瓦斯防治的可行性。并进一步讨论了基于本模型如何进行合理监测矿井瓦斯浓度，指导现场科学防治瓦斯灾害。

Flowing distribution of gas in mine passageways

Based on the map fundamental, a mathematic model about gas flowing in the mine passageways is set up. Analyzing the property of the model, a method to cure mine gas is worked out. It was illustrated through a real test in a mine that the means is useful for preventing gas threat.
