外错式低位巷穿层抽放治理瓦斯技术

摘要

院八矿探索使用外错式低位巷穿层抽放治理突出采煤工作面瓦斯，保证了采面的正规循环作业，杜绝了瓦斯超限，保证了矿井安全生产，并为以后采面的抽排巷设计提供了依据。%The Eight Mine uses outside-type low lane cross-layer drainage to governance prominent coal mine workface gas, which ensuring the regular cycle work of coal mine face,avoiding gas overrun,ensuing mine safety production, and provides a basis for the design of future mining lane pumping surface.
