瓦斯抽放在掘进巷道中的应用

Application on Gas Drainage in the Excavation Roadway

瓦斯突出是严重威胁煤矿安全生产的主要自然因素之一。瓦斯涌出形式和涌出量对矿井设计、建设和开采都有重要影响。瓦斯抽放是保证高瓦斯矿井安全生产的有效途径。介绍了瓦斯抽放的现状与作用,根据我国《矿井瓦斯抽放技术规范》的有关规定及某矿实际情况,分析评价对其进行瓦斯抽放可行性,提出在该矿410061下巷采用综合瓦斯抽放的技术,对掘进过程中的瓦斯涌出问题进行处理,取得了良好的效果,为煤矿瓦斯治理提供了新的方法及思路。

Gas outburst is one of main natural factors of serious threat safety production in coal mine.The gas emission form and emission quantity has important influence to design,construction and mining of the mine.Gas drainage is the effective way to ensure production safety in high gassy mine.Introduces the present situation and the effect of gas drainage,according to relevant regulation of＂ Gas drainage under suction technical specifications＂ in our country and the actual conditions in a mine,analyzes and evaluates the feasibility of gas drainage,puts forward adopt comprehensive gas drainage technology in the 410061 next lane of the mine,deal with the gas emission in tunneling process,provides a new method and idea for gas control of the mine.
