高瓦斯掘进工作面的瓦斯治理方法研究

Research on Gas Control Methods at Tunneling Working Face with Concentrated Gas

为了解决高瓦斯影响巷道施工的问题,针对煤矿开采深度不断增加而造成瓦斯含量逐渐增高,严重制约了巷道掘进,采取了科学合理调整风量、单风机转为双风机等措施,有效降低了瓦斯浓度,结果表明,采取上述措施后解决了瓦斯大制约巷道掘进的问题,同时解决了空气中灰尘较大的问题。

Concentrated gas exerts an impact on tunnel construction. With the increase in the depth of coal mining, gas content is increasing gradually and seriously restricts the drivage. This paper adopted measures of a scientific and reasonable adjustment of air volume and the use of double fan in stead of single fan, effectively reducing the gas concentration. The results showed that the restrictions of concentrated gas to tunnel construction and huge dust in the air could be solved by taking these measures.
