摘　　要：为了有效地预测煤矿井下奥灰突水灾害,在MTI奥灰水监测预报方法基础上,提出了煤矿井下奥灰水突水危险区域的判别方法。该方法采用有限元方法对矿区以及周边区域煤层底板含水层建立渗流模型并且进行数值模拟计算,最终计算结果应用于霍州煤电集团李雅庄煤矿突水预测。结果表明:以所有节点突水危险判别指标平均值的10%、20%、30%作为界限,将计算区域划分为不同等级的突水危险区域。该预测方法适用于不同水文地质条件的矿区进行煤矿奥灰水突水危险预测。In order to effectively predict the Ordovician Limestone water inrush occurred in the underground mine,based on the study on the MTI Ordovician Limestone water monitoring and prediction method,a distinguishing method of the Ordovician Limestone water inrush danger area in the underground mine was provided. The method with the finite element method was applied to establish a seepage model of the seam floor aquifers in the mining area and the surrounding region and a numerical simulation calculation was conducted. The calculation results were applied to the prediction of the mine water inrush in Liyazhuang Mine of Huozhou Coal and Electric Power Group. The results showed that based on the distinguishing index average value of the all node water inrush danger was 10%,20% and 30% as the limit,the calculation region was divided in to different grade water inrush danger region. The prediction method suitable to the mining area with different hydrogeologic condition could be applied to predict the mine Ordovician Limestone water inrush.
