综放面治理瓦斯工艺实践

Craft Practice of Control Gas in Fully-mechanized Top-coal Caving Workface

通过对五阳煤矿综放工作面治理瓦斯所用各方式的比较分析 ,着重介绍了综放工作面E型与h型两种通风方式治理瓦斯的主要优缺点及瓦斯流向特征 ,证明了综放面采用h型通风方式在治理瓦斯效果及技术经济效益方面都优于E型通风方式。

Based on comparative analysis of varions way in control gas in fully-mechanized workface of Wuyang coal mine,this article intro duces advantage and shortcoming of control gas with two kinds ventilation ways and feature of gas direction in E and h fully-mechanized workface,proves using h ventilation way in fully-mechanized workface in control gas,has a good effect and economic benefit with h ventilation way.
