峰峰煤田大青、奥灰含水层是威胁矿井生产的两个主要含水层。由于两含水层层间距较近,在构造断裂的影响下不仅互相补给,水力联系密切,使水文地质条件复杂化,同时随着开采水平的增大,底板的突水威胁也越来越大。因此,我局下三层煤约16亿吨,占总地质储量的40％左右至今未能开采。鉴于上述情况,如何判别 Fengfeng Coalfield Daqing, Ordovician aquifers are the two main aquifers that threaten mine production. Due to the close spacing between the two aquifer layers, the hydrogeological conditions are not only mutually replenished but also closely linked to each other under the influence of structural faults, which complicate the hydrogeological conditions. At the same time, as the mining level increases, the intrusion of the floor plate becomes more and more serious. Therefore, I Bureau of the next three layers of coal about 1.6 billion tons, accounting for about 40% of the total geological reserves so far failed to mining. In view of the above, how to judge
