摘要
X40702采面回采初期遇到瓦斯超限严重等问题.积极采用加大配风量、本煤层预抽、上隅角抽放和风排等多种方法综合治理瓦斯,最终解决了工作面瓦斯超限问题,为该矿今后的"一通三防"安全生产打下了一个坚实的基础,为以后的工作积累了宝贵的经验。
In the early recovery of X40702 face mining encountered serious problems, such as gas gauge. Actively used with increasing air volume, the pre-pumping, the upper corner of drainage and wind row, and so many ways for comprehensive management of gas, finally solute the gas gauge problem. Laid a solid foundation for the "ventilation and three defenses" of production safety and accumulated valuable experience for future work.
