靖煤公司大水头煤矿是甘肃省国有重点 煤矿，为高瓦斯矿井，瓦斯含量高，煤层易自燃发火， 科学合理的通风技术是解决大水头矿井瓦斯问题的主要 手段。本课题结合矿井实际，一是通过对大水头矿通风 阻力和风机性能的实测，解算通风网络，深入分析高瓦 斯矿井网络系统现状及其稳定性，优化矿井通风系统； 二是通过对高瓦斯综放开采采空区瓦斯运移规律的实验 研究，提出了适合大水头矿井综放开采的B型通风模式 ；三是研究解决高瓦斯软煤层中布置大断面长巷道的掘 进通风技术并进行经济分析。 该课题将矿井通风系统、采煤工作面通风模式与掘进通 风方式等三大板块有机结合进行集成化研究，极具广泛 性和代表性，对大水头煤矿解决安全生产管理的难题具 有重要的现实作用，对促进我国相同条件下高瓦斯矿井 安全生产也具有重要意义和推广价值，具有巨大的经济 效益和社会效益。

On the basis of newly achievements in researches in the field of mine ventilation, a study on the ventilation technology for Da Shuitou high methane mine is put forward. Using the result of resistance survey, fan capability and calculation of ventilation network, the stability of ventilation network is analyzed and optimized. Base on the gas delivery in gob caving longwall face, B ventilation pattern for the Da Shuitou is proposed, and ventilation technologies for long flexible coal bed to solve the high methane. Considering the practical needs of the coal mine, for the technique path, we use the ventilation theory, calculation software and the result of some simulation. This study combine the ventilation system to ventilation pattern in work face and digging laneway. It is helpful not only for the Da Shuitou to improve it’s safety actuality but for the other mines with high methane.
