浅谈高瓦斯矿井瓦斯分级治理工作

Discussion on Gas Classification Control of High Gas Mine

高瓦斯始终是现代矿井主要安全隐患,在掘进巷道施工过程中,为确保瓦斯可控,各个煤矿结合自身情况制订了很多办法,通过有效抽采、钻孔释放、CO2气相压裂等分级治理的方法,降低煤层瓦斯压力和瓦斯含量,将高瓦斯、煤与瓦斯突出煤层变为低瓦斯、无煤与瓦斯突出危险,确保掘进作业的安全高效。

High gas has always been a major safety hazard in modern mines.In the process of driving tunnels,in order to ensure that the gas is controllable,each coal mine has formulated a lot of methods in accordance with its own situation.They reduce gas pressure and gas content of coal seam through effective extraction,drilling release,CO2 gas fracturing and other grading treatment methods,and change the high gas,coal and gas outburst coal seam into low gas,no coal and gas outburst danger,to ensure the safety and efficiency of the tunneling operation.
