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陶系灰岩岩溶水的威胁 ,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 。During the mining of the lowest coal bed in North China, especially coal fields at the eastern and southern feet of Taihang mountain, the mining faces are commonly threatened by Ordovician limestone aquifer and water disasters are happened very frequently. The traditional techniques for predicting water invasion are facing unprecedented challenges. Model for predicting water invasion from coal bed is established herein by analyzing the hydrogeologic conditions of floor plate in coal bed, factors of water invasion, mechanism of water invasion and aided by GIS. The outcomes are satisfactory.
