摘　　要：屯兰煤矿是煤与瓦斯突出矿井,瓦斯涌出量大,上隅角瓦斯治理困难。为解决这一通风难题,该矿采取沿空留巷抽采措施进行作业。实践证明,该技术解决了上隅角瓦斯积聚隐患,保障了矿井高产高效。Tunlan Coal Mine is a coal and gas outburst mine, the amount of gas emission is large, and it is difficult to control the gas in the upper corner. In order to solve this problem, the mine adopted the measures of gob side entry extraction. The practice showed that the technology solves the hidden danger of gas accumulation in the upper corner and ensures the high production and efficiency of the mine.
