| 摘 要： | 煤矿生产中的瓦斯灾害,以往是指煤层掘进或回采工作面的瓦斯突出或涌出,以及煤系地层中砂岩掘进时的二氧化碳突出。而非煤系地层岩巷掘进中的煤岩突出及大量瓦斯的快速涌出,则是随着煤矿生产的发展而新出现的一大灾害,不容忽视。井巷掘进中,瓦斯不断涌出,其型式分缓变、突变、突增渐缓三种。以瓦斯地质的观点,对松藻矿务局岩巷掘进中瓦斯灾害特征及预防对策进行了讨论。

| Abstract: | Gas hazard in coal production is gas inrush from a stope face and CO2 inrush from driven sandstone in coal-bearing formation. By the gas hazard herewe mean gas inrush in opening drifting in rock series without coal, it is a great and new geological hazard in coal production. Gas emission in opening drifting may be divided into three types. This paper makes an approach to the feature of gas hazard in the opening drifting in the Songzao Mining and countermeasure. |
