摘要:
以李雅庄煤矿采空区瓦斯治理效果为研究目的，对2#煤层224、601、603工作面分别采用了瓦斯尾巷、高位钻场、高位抽放巷三种方法进行实测与分析，通过现场实践对抽采参数以及施工、管理进行分析。结果表明：通过抽采参数的对比分析，从抽采浓度平均值上，高抽巷为24.5%，明显高于高位钻场的15%，瓦斯尾巷为6.3%；从抽采纯流量平均值上，高抽巷为2.03m3/min，高于高位钻场的1.95 m3/min，瓦斯尾巷的1.66 m3/min；从抽采率平均值上，高抽巷为57.2%，高位钻场为45.6%，明显高于瓦斯尾巷的23.1%。通过施工、管理的对比分析，布置瓦斯尾巷，必须多掘一条巷道，投资大，增加管理难度、安全隐患等；高位钻场坡度大，人员、设备上下困难，回采过程中钻孔易被压实；高抽巷便于管理、观测，易于控制瓦斯抽出量。在李雅庄煤矿现有的综合条件下，高抽巷能起到最好的瓦斯治理效果。
Abstract:
Taking the effect of gas control in goaf of Liyazhuang mine as the research purpose, by respectively using the methods of gas tail roadway, high location drilling field and high drainage roadway on the 224, 601 and 603 working faces, the control effect was measured and analyzed. The results showed that: from the average of extraction concentration, the value of high drainage roadway is 24.5%, which is significantly higher than those of high level drilling (15%) and the gas tail roadway (6.3%); from the average of pure drainage flow, the value of high drainage roadway is 2.03m3/min, which is higher than those of high level drilling (1.95 m3/min) and gas tail roadway (1.95 m3/min); from the average of drainage rate, the value of high drainage roadway is 57.2%, which is higher than those of high level drilling (45.6%) and the gas tail roadway (23.1%). Through comparing the construction and management of three methods, arranging gas tail roadway must drive a new tunnel, with a great investment and management difficulties; arranging high location drilling field goes against pedestrian and is difficult to transport people and equipment, and the drills may be compressed easily; but arranging high drainage roadway is easy to be managed and observed, and the drainage quantity is easy to be controlled. Contrastively analyzing the control methods, high drainage roadway is the best one for Liyazhuang coal mine.
