瓦斯抽放启封巷道新技术探索与实践

在煤矿井下生产过程中,经常需要启封封闭墙,掘进巷道临时停风或长期停风后,造成巷道内积聚大量的高浓度瓦斯,需要进行排放,而排放方法不妥或因其它因素,很容易发生安全事故。任楼煤矿采用瓦斯抽放启封巷道新技术,实现了封闭巷道安全启封和瓦斯排放工作。

Unsealing of Gas Drainage Tunnel Exploration and Practice of New Technologies

In coal mine production process, often unsealed closed walls, roadway or long - term temporary stop the wind after the wind stopped, resulting in accumulation of a large number of roadway a high concentration of gas, gas emissions needed, and discharge method is wrong or because of other factors, it is prone to accidents. Coal Mine Gas Drainage Renlou unsealed roadway with new technology, to achieve the dosed unsealed roadway safety and gas emission work.
