摘　　要：以西曲矿19201工作面为研究对象,对该工作面的瓦斯治理措施进行探讨。19201工作面主要瓦斯来源为本煤层和采空区瓦斯,因此针对性的采用本煤层顺层长钻孔+上隅角埋管进行瓦斯抽采,并对瓦斯抽采效果进行分析。结果表明,建立瓦斯抽采系统后,19201工作面的风排瓦斯量和上隅角瓦斯浓度明显降低,从而为工作面的安全生产提供了保障。Taking No.19201 working face in Xiqu Mine as the research object,the gas control was discussed.Since the gas in No.19201 working face is mainly from the current coal seam and goaf,the gas drainage with long boreholes of bedding in the current coal seam and buried pipelines in upper corner was adopted.In addition,the gas drainage effect was analyzed.The results show that,with the establishment of the gas drainage system,the gas emission volume by ventilation and the gas concentration in the upper corner were significantly reduced,which could guarantee the safe production on the working face.
