根据工作面地质及开采条件,通过现场测定I010202工作面煤层可解吸瓦斯含量,完成了工作面采前瓦斯含量测定工作,在此基础上应用分源预测法对工作面回采期间瓦斯涌出量进行了计算和分析,并对工作面回采期间需要采取的治理措施进行了可行性研究,最后给出了以“瓦斯抽采为主,以调整风量和生产能力为辅”的综合瓦斯治理措施。
According to the geology and mining conditions of working face, the gas content of coal seam I010202 working face can be determined by on-site measurement, and the determination of gas content before working face was completed. Based on this, the gas emission amount during working face mining Calculated and analyzed, and carried out feasibility study on the measures to be taken during the process of face mining, and finally gave the comprehensive measures of gas control taking “gas drainage as the main method to adjust the air volume and production capacity as the auxiliary ” .
