摘要
研究目的:根据隧道瓦斯与煤矿瓦斯防治方法、控制标准和主要指标的不同,研究一种有别于煤矿瓦斯等级划分的隧道瓦斯等级划分新方法,并依据划分的等级来确定隧道的不同防爆设备和瓦斯管理制度。研究结论:通过对施工通风和稀释瓦斯浓度原理分析及试算,对瓦斯隧道提出了一种新的等级划分方法,不是单纯以瓦斯涌出量为标准,而是结合隧道自身状况和施工通风布置形式来定义瓦斯隧道等级,该方法是一个多元素决定的等级标准。
Research purposes： In this paper, the difference between the gas preventions of the tunnel and coal mining and the standard and main indexes for control of tunnel gas are pointed out and a new method different from the grade repartition of mining gasis presented for the grade repartition of the tunnel gas and application of this method can determine the antiknock device and the gas control management system. With this method, it is easy to operate and guide the design, construction and management. Research conclusions ：The method presented in this paper does not only takes the volume of the gas emission as the standard, but also considers the tunnel condition and the layout pattern of ventilation devices to define the gas grade, so with this method to determine the gas grade, many factors should be considered.
