对上庄煤矿3101工作面回采过程中瓦斯涌出状况进行了分析和研究,结合煤层及瓦斯赋存条件,首先采取高位钻孔和上隅角抽放相结合的方法保证当前的生产要求,在瓦斯高抽巷形成后,从根本上解决了瓦斯超限的问题。矿井总回风巷的稀释瓦斯的能力接近极限,采取地面瓦斯排放孔,把抽出的瓦斯利用专用管道直接排出利用。 Based on the analysis and research on the gas emission condition during the mining process of 3101 working face in Shangzhuang Coal Mine, combining with the coal seams and gas occurrence conditions, firstly, the combination of high-level drilling and upper corner gas drainage is adopted to ensure the current production requirements. After the formation of high pumping Lane, a fundamental solution to the problem of gas overrun. The total return airway mine dilution capacity of the gas close to the limit, to take the ground gas discharge holes, the extraction of gas using a dedicated pipeline directly discharged.
