Abstract
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
