摘　　要：为安全开采下组煤 ,详细分析了矿区奥灰水文地质条件。以研究煤层底板突水因素、突水机理为切入点 ,利用地理信息系统技术 ,对下组煤开采之前奥灰突水的危险性进行了预测 ,即可分为 3个区 (安全区、可能突水区、突水区 ) ,同时提出下组煤先期开采的范围为 - 2 1 0The hydrogeological conditions in Xingtai coal mine are analyzed in order to mine the lowest coal seam under safe conditions.The study is focused on the affecting factors and mechanism of water inrush from coal seam floor.The risk analysis for water inrush from Ordovician limestone before mining has been made by using GIS.The mining area is divided into three parts,i.e.safe area,potential water inrush area and water inrush area.Meanwhile the range for initial mining is delineated.
