沿空留巷Y型通风瓦斯治理效果分析

Analysis on Gas Control Effect of Y-type Ventilation in Gob-side Entry Retaining

瓦斯治理始终是煤矿生产作业过程中重点关注问题,相较于以往U+L、U型通风方式,沿空留巷Y型通风可以进一步提升矿井风量,消除以往掘进速度慢、工程量大等问题。本文以某矿井3107工作面为例,对沿空留巷Y型通风瓦斯治理效果进行深入探析。

Gas control has always been a key concern in the process of production operations in coal mine.Compared with the previous U+L and U-type ventilation methods,Y-type ventilation for gob-side entry retaining can further improve the mine air volume and eliminate the problems of slow tunneling speed and large quantities of work in the past.Taking 3107 working face of a mine as an example,this paper makes an in-depth analysis on the effect of Y-type ventilation gas control in gob-side entry retaining.
