摘要
针对五阳煤矿煤层松软、透气性低、瓦斯抽采困难等问题,以瓦斯抽采技术为主要研究内容,结合该矿生产现状,应用RFPA软件建立模型,通过数值模拟对瓦斯抽采效果的影响因素进行了系统的分析。研究了边掘边抽的抽采工艺,优化了瓦斯抽采系统的抽采钻孔的合理夹角,对瓦斯抽采效果进行了分析。在此基础上,针对目前瓦斯抽采系统存在的主要问题,提出解决方案,以提高瓦斯抽采率,确保煤矿安全高效生产。
To counter the problems such as the soft coal seams, seams with low permeability and difficult gas drainage in Wuyang Mine, the systematical analysis on the influence factors of gas drainage effect was conducted in this paper by taking the gas drainage technology as the main research content, combining with the production status of the mine, applying the model built with RFPA software and through numerical simulation. Research was made on the gas drainage technology while driving, the reasonable angle of the gas drainage hole was optimized, and analysis was carried out on the gas drainage effect. On this basis and directed against the main problems of the current gas drainage system, solutions were proposed so as to improve the gas drainage rate and ensure the safe and efficient production of the Mine
