摘    要:由于对兖州矿区3号煤层顶板砂岩含水性能认识不足,造成了多次矿井的突水事件,甚至淹井停产。分析了兖州矿区3号煤层顶板砂岩的物质组成、孔隙微观特征和岩石力学特征、渗透性能、富水性情况的基础上,利用GIS多元信息拟合技术对3号煤层顶板砂岩含水层进行了突水危险性进行了初步评价。该研究对类似条件下其他矿区水害防治工作具有一定的参考价值。

关 键 词:兖州矿区  煤层顶板  含水层  水文地质特征

Abstract:The inadequate understanding of the No.3 coal roof sandstone aquifer in Yanzhou Mining Area,lead to a number of water invasion events,even the shaft inundation or wells shutdown.This article analyzed the material composition,micro-pore characteristics,and the characteristics of the rock mechanics and then studied the permeability of the No.3 coal roof sandstone in Yanzhou Mining Area.Finally,using GIS multiple information fitting technology we made a preliminary evaluation for the water invasion danger of the No.3 coal roof sandstone aquifer.The research has evaluated the danger of water invasion for the No.3 coal roof sandstone aquifer.
Keywords:Yanzhou mining area  coal roof  aquifer  hydrogeologic characteristics
