回采面通风系统优化与瓦斯治理分析

Ventilation System Optimization and Gas Control Analysis of Mining Face

以回采面通风系统优化与瓦斯治理为对象开展分析探究,结合具体工程实际,在分析原作业面U型通风不足的基础上,提出使用"Y型通风+采空区抽采"的瓦斯治理优化模式,并分别对沿空留巷Y型通风设计和作业面瓦斯抽采设计展开探究,希望能够为其他矿井相似工程的开展提供借鉴与参考。

The optimization of ventilation system and gas control in the mining face were studied.Combined with specific engineering practice,based on the analysis of the lack of U-type ventilation in the original working face,this paper put forward the gas control optimization mode of"Y-type ventilation+goaf drainage",and explored the Y-type ventilation design of gob-side entry retaining and the gas drainage design of working face respectively,hoping to provide reference for the development of similar projects in other mines.
