摘　　要： 华北地区特别是太行山东麓、南麓的煤田在开采下组煤的过程中普遍地受到底板奥灰岩溶水的威胁 ,突水淹井事故时有发生 ,传统的底板突水预测方法受到了前所未有的挑战。本文从分析煤层底板水文地质条件、突水因素、突水机理为切入点 ,在GIS的支持下 ,建立了煤层底板突水预测模型 ,效果较好。 In coal mines in regions of northern China,especially at eastern and sourthern side\|hills of Taihang mountain,water bursts often occur because the bed bottoms of mines there are usually constituted by Ordovician limestone which can be easily eroded by underground water.The traditional methods for forecasting water burst become insuffient in effectiveness.Based on anlysis of geohydrological conditions,water burst factors and water burst mechanism,a GIS\|based water burst forecasting model has been established which brings good results in the practice.
