摘要
通过分析综采放顶煤工作面瓦斯涌出特点及影响因素,探索出通过改变回风巷和尾巷的风量及这两者之间的静压差值,有效地解决上隅角瓦斯局部积聚难题,对上隅角瓦斯局部积聚进行治理,有极大的实践意义和现实意义。
This paper through the analysis of gas emission features in mechanized mining face and the impact factors of gas emission in mechanized mining face. Explore the static pressure by changing value in the return lane and end lane wind, and govern the local accumulation of gas on the comer. This method can solve the local accumulation of the upper comer gas better, Govern the comer gas local accumulation in this manner has a scientific and reasonable, convenient operation and stable and reliable characteristics, and has great practical significance and practical significance.
