摘要
针对高瓦斯极近距离煤层群开采综采工作面瓦斯涌出量大、治理难度高的问题,采用综合抽采瓦斯方法进行瓦斯治理,有效地降低了采煤工作面、回风流及上隅角的瓦斯涌出量,提高了通风生产能力,瓦斯治理效果明显,给安全生产创造了良好的条件。实践证明,综采工作面瓦斯综合治理技术有效控制了瓦斯超限,保证了矿井的安全高产高效。
Due to high concentration gas inrush and the treatment complexity gas in very near adjacent layers,comprehensive gas recovery method is adopted to effectively reduce the inrush of gas in coal mining face,upper corners of the airway. improves the ventilation production capacity,gas control effect is obvious. Practice proves that comprehensive treatment effectively controlled the gas overrun,the safety and high efficiency of the mine are guaranteed.
