【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。
[Abstract]:In order to effectively predict the Ordovician water inrush disaster in coal mine, based on the MTI Ordovician water monitoring and forecasting method, a method to distinguish the dangerous area of Ordovician water inrush in coal mine is put forward. The seepage model of coal seam floor aquifer in mining area and surrounding area is established by using finite element method and the numerical simulation calculation is carried out. The final calculation result is applied to the prediction of water inrush in Liyazhuang coal mine of Huozhou Coal and Power Group Group. The results show that the calculated area is divided into different grades of water inrush danger area with 10% 20% of the average value of water inrush hazard index of all nodes as the limit. The method is suitable for predicting the water inrush danger of Ordovician ash in coal mine under different hydrogeological conditions.
