九里山矿14141工作面瓦斯涌出量分析

Analysis of Gas Emission in the 14141 Working Face in Jiulishan Mine

为分析综采工作面瓦斯涌出量在割煤过程中的变化规律,在九里山矿14141工作面回采初期开展了瓦斯涌出量预测研究。研究表明九里山矿14141工作面主要瓦斯涌出源为割煤机落煤瓦斯涌出和采空区瓦斯涌出,当前施工组织方式下,工作面通风能力和抽采能力能够满足要求,但应注意合理控制割煤速度和作业循环,加强采空区和上隅角管理。

In order to analyze the variation law of gas emission in the coal cutting process, the prediction of gas emission was carried out in the early stage of 14141 working face in Jiulishan Mine. Through study, the main gas source of Jiulishan Mine 14141 face is from cutting coal gas emission and coal goaf gas emission, and based on the current construction, working face ventilation and extraction ability can meet the requirements, but should pay attention to the reasonable control of coal cutting velocity and the operation cycle, and strengthen the management of mined-out area and the upper corner.
