煤矿双U型回采工作面通风措施探讨

Probe into the Ventilation Measures for Double U Type Mining Faces in Coal Mine

通过对潞安矿区余吾煤业双U型回采工作面通风措施的探讨,得出结论:该矿采用双"U"型通风方式,在解决瓦斯超限、改善工作面作业环境等方面取得非常显著的效果,采用双巷进风、双巷回风的措施能够增强回采工作面抵抗灾害的能力,能够保障回采工作面的安全生产。

This paper probes into the ventilation measures for double U type mining faces in Yuwu Mining Company of Lu＇an mining area, and draws a conclusion that the double U type ventilation pattern adopted by this company has obtained very significant results in aspects of solving the gas overrun, and improving the working environment of mining faces, etc., adopting the measures of double channel air intake and air return can enhance the anti-disaster ability of the mining faces, and insure the safe production of the mining faces.
