低瓦斯矿井高瓦斯区域工作面瓦斯治理技术

Gas Control Technology of Working Face in High Gas Area of low Gas Mine

为了解决低瓦斯矿井高瓦斯区域工作面瓦斯治理的问题,针对四侯煤业3105工作面在回采期间需通过多个地质异常区域,存在工作面上隅角瓦斯超限的隐患,通过建立瓦斯监测体系,采取上隅角切顶控制悬顶、上隅角瓦斯抽放及高位钻孔抽采等瓦斯治理技术措施,可以有效解决工作面上隅角瓦斯超限问题。

In order to solve the problem of gas control in the working face of high gas area in low gas mine,in view of the fact that the 3105 working face of Sihou Coal Industry needs to pass through many geological abnormal areas during the mining period,there is a hidden danger that the gas in the upper corner of the working face exceeds the limit.Through the establishment of gas monitoring system and the adoption of gas control technical measures such as top corner cutting control hanging roof,top corner gas drainage and high-level drilling drainage,the problem of gas overrun in the upper corner of the working face can be effectively solved.
