“Y”形通风工作面瓦斯浓度分布规律及瓦斯治理技术分析

Gas Concentration Distribution Law and Gas Control Technology in "Y" Type Ventilation Working Face

针对应用“Y”形通风系统时,在沿空留巷密闭墙和上部空间中存在瓦斯聚集现象,给煤矿开采造成了一定的安全隐患的问题,在介绍案例煤矿的基本情况,对工作面瓦斯浓度分布规律进行模拟,提出科学的瓦斯治理技术,以期望可以为其他煤矿的生产通风工作提供借鉴作用。

In view of the problem that there is gas accumulation in the closed wall and upper space of the goaf retaining roadway when the"Y"type ventilation system is applied,which has caused certain safety hazards for coal mining,the basic situation of the case coal mine is introduced,the distribution law of the gas concentration in the working face is simulated,and the scientific gas control technology is proposed,which is expected to provide a reference for the production and ventilation work of other coal mines.
