摘要
通过对济宁二号矿瓦斯排放工作的分析,根据井下的巷道具体情况及瓦斯含量,采取全风压通风系统排放、局部通风机排放、钻孔压风排放等方法,达到了快速、安全的目的。
Through the analysis on gas discharging in Jining coalmine II, and on the basis of the gas density and the specific conditions of roadways arrangement, this aritcle, in order to achieve promptness, safety and high efficiency, integrates many effective gas discharging methods, such as full pressure ventilation, auxiliary fans and drill-holl ventilation, and so forth.
