新建煤矿“一面三巷”瓦斯治理技术

“One Side,Three Roadways”Gas Control Technology in Xinjian Coal Mine

针对新建煤矿瓦斯赋存条件,在瓦斯致灾因素和瓦斯赋存特征分析基础上,提出新建煤矿“一面三巷”瓦斯治理技术,以“一入一回+底抽巷”的方式,形成一个工作面三条通风巷道,并通过底抽巷进行超前预抽瓦斯。该技术在新建煤矿40031工作面应用后,瓦斯治理效果明显,保证了矿井的安全生产。

According to the gas occurrence conditions of Xinjian Coal Mine,based on the analysis of gas disaster factors and gas occurrence characteristics,the gas control technology of"one side,three lanes"in Xinjian Coal Mine is put forward.By the way of"one entry,one return and bottom drainage lane",three ventilation lanes are formed in one working face,and the gas is pre drained in advance through the bottom drainage lane.After the application of this technology in the 40031 working face of the new coal mine,the effect of gas control is obvious and the safety production of the mine is guaranteed.
