摘　　要：以贺昌煤矿为例,从瓦斯涌出现状及预测情况、通风能力、资源利用和环保三个角度,验证了抽放瓦斯的必要性以及可行性,介绍了本煤层瓦斯抽放、邻近层瓦斯抽放、采空区瓦斯抽放等抽放方法。工程实践表明,瓦斯抽放量可达30 m^3/min,抽放率约53.4%,使瓦斯治理工作稳步推进,增强了矿井安全可靠度。Taking Hechang coal mine as an example, verifies the necessity of gas drainage from three aspects, which are the present situation of gas outburst and prediction situation, ventilation ability, and resource utilization and environmental protection, and introduces the drainage methods：gas drainage from original coal seam, from neighboring layers, and from mined -out areas. Engineering practice shows that the gas drainage amount can reach 30 m3/min, and the efficiency is 53.4% , which leads that the gas controlling work steadily improves, and security reliability is enhanced.
