一、井陉三矿的瓦斯与突水井陉三矿是一个具有70多年历史的老矿井,现在主要开采太原组最下煤层,受奥灰水威胁较大,一般要带10～35 kg/cm~2压力开采,稍有疏忽就有突水的可能。在长期的生产实践中,三矿地质工作者对煤层瓦斯与底板突水的关系进行了探索,从多年的经验中总结出,瓦斯含量高的地区,水文地质条件简单,在采掘过程中一般不会发生底板突水事故,即便发生底板 First, the mine gas well and water inrush mine wells Third, mine is a mine with a history of more than 70 years of the old mine, the main coal mining is now the lowest Taiyuan group, threatened by the Austrian gray water, generally with 10 ~ 35 kg / cm ~ 2 pressure mining, there is the possibility of water inrush. In long-term production practice, the three mine geological workers explored the relationship between coal seam gas and water inrush from the floor. From years of experience, it is concluded that the areas with high gas content have simple hydrogeological conditions and are generally not Floor water inrush incidents, even when the floor occurs
