外错式低位巷穿层抽放治理瓦斯技术

Outside-type Low Lane Cross-layer Drainage Governance Gas Technology

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.
