U型通风系统采空区瓦斯抽采技术分析

Analysis of Gas Drainage Technology in Goaf of U-type Ventilation System

对于存在较高瓦斯涌出量的矿井,U型通风系统具有较小的通风量,因此瓦斯易在工作面的上隅角积聚,从而阻碍了矿井安全生产目标的实现。据此,本文结合实际案例,浅析U型通风系统采空区瓦斯抽采技术,以实现瓦斯与煤的高效共采。

For mines with high gas emission, the U-type ventilation system has smaller ventilation, so gas is easy to accumulate in the upper corner of the working face, which hinders the realization of the goal of mine safety production. Based on this, combined with practical cases, this paper makes a brief analysis on the gas drainage technology in goaf of U-type ventilation system, in order to realize the efficient co-mining of gas and coal.
