摘要
在煤矿进行采掘活动过程中,不可避免的会出现临时停风的掘进工作面和启封封闭巷道等情况,因而必须进行瓦斯排放工作。通过对瓦斯排放方法的研究,为1201工作面瓦斯排放方法进行了合理地选择。
In the mining process it is inevitable that ventilation fans stop occasionally in driving face and sealed roadways are reopened,so gas drainage is necessary.By the analysis on the different methods,a rational gas drainage approach is selected for No.1201 working face.
