摘　　要：结合某矿2901工作面的地质条件和瓦斯基础参数,分析了2901工作面的瓦斯来源和影响瓦斯异常涌出的因素。针对工作面瓦斯涌出来源,制定了合理配风、局部通风、高位钻孔抽放、上隅角埋管抽放、本煤层钻孔预抽放等综合瓦斯防治技术措施,成功解决了工作面上隅角和回风巷瓦斯超限问题。Combined with the geological conditions and gas parameters of the 2901 working face, the gas source of 2901 working face and the factors affecting gas emission were analyzed. For gas emission source, reasonable wind distribution, local ventilation, high level borehole pumping, upper corner buried drainage pipe, the coal seam drilling predrainage gas comprehensive prevention and control measures be made, resolved the problem of gas over limited in the top corner and return roadway.
