摘要
为了探究煤与瓦斯突出后在上行风巷道引起并联支路风流逆流的影响因素,对矿井并联上行风巷道的模型进行假设,并通过对巷道中空气的受力分析,进行静态和动态的推导,得出影响风流逆转发生时间的关系式。从式中得出影响风流逆转的几个因素,并从这些因素出发,提出矿井防止瓦斯致逆流的措施。
In order to study factors on flow reversals in bypass branch of ascensionally venti- lated roadway after coal-and-gas outburst. Assumptions are made in the model of parallel road- ways. Through force analysis on air in roadways, and derivation of static and dynamic models, e-quality including when the reversal happens is concluded. There is some factors influenting the reversal from the equality. Proposing measures to prevent reversals is based on these factors.
