摘要
王家岭煤矿为新建矿井,鉴于其井下实测瓦斯含量数据和回采瓦斯涌出数据较少的实际,通过煤层瓦斯赋存影响因素的综合分析,确定矿井2#煤层瓦斯赋存主控因素,并进行煤层瓦斯含量预测。在此基础上,进行工作面回采瓦斯涌出量预测,论述回采工作面瓦斯抽采的必要性和可行性,并考察分析了工作面本煤层及采空区瓦斯抽采技术在王家岭煤矿的实践。
Wangjialing coal mine is a new mine, there are very little gas content data and gas emission data. By analysising the influence factors of gas occurrence, get the most important factor of No.2 coal seam, and predict the gas occurrence of original zones. Predict the gas emission of mining face using predicted method by different gas source, discuss the necessity and feasibility of gas drainage in mining face, study the project practice of coal seam gas drainage and goaf gas drainage in Wangjialing coal mine.
