摘要

麦捷煤业重点开采15号煤层150505综放工作面，为保证该工作面顺利回采，对该工作面瓦斯涌出量进行预测。通过分析研究割煤、放煤、采空区以及邻近煤层瓦斯的相对瓦斯涌出量，计算预测150505综放工作面的相对瓦斯涌出量和绝对瓦斯涌出量。根据预测数值，结合相关规定，确定了“单U通风+高抽巷抽采+顶板、裂隙带钻孔抽采”的瓦斯治理模式。实践表明，设计的瓦斯治理方案科学有效，保证了工作面安全高效开采。
Abstract

order to ensure the smooth mining of the 150505 fully mechanized caving face of No.15 coal seam in Maijie Coal Industry, the gas emission of the working face is predicted. By analyzing and studying the relative gas emission of coal cutting, coal caving, goaf and adjacent coal seams, the relative gas emission and absolute gas emission of 150505 fully mechanized caving face are calculated and predicted. According to the predicted value, combined with the relevant regulations, the gas control mode of ' single U ventilation + high drainage roadway extraction + roof and fracture zone drilling extraction ' was determined. Practice shows that the designed gas control scheme is scientific and effective, which ensures the safe and efficient mining of the working face.
