某矿煤巷掘进时煤与瓦斯突出的防治

The Prevention of Coal and Gas Outburst about Some Coal Mine in Driving

某矿是高瓦斯矿井,在煤巷掘进中需要进行煤与瓦斯突出的防治。文章通过对煤巷掘进进行分类管理并制定了相应的"四位一体"防突措施。经过在2号回风大巷掘进时对煤与瓦斯突出的防治试验,取得了一定的成果,在2号回风大巷中达到了抽、掘生产平衡,加快了巷道的掘进速度。

Some Coal Mine is a high-gas coal mine and needs to control the coal and gas outburst in coal road tunneling. Based on the coal lane tunneling classification management and made the ＂four in one＂ outburst prevention measures. Through the control test in number 2 return air roadway tunneling of the coal and gas outburst, and achieved certain results, in the number 2 return air roadway reachedpumping, excavating production balance, accelerate the speed of roadway.
