根据滕县煤田滕南矿区煤层开采现状,针对太原组煤层开采受底板突水威胁的问题,分析了滕南矿区的自然地理、地层、构造、水文地质条件及特征,按照水文地质单元划分依据,并将其划分为3个二级、8个三级水文地质单元。通过对滕南矿区水文地质单元水文地质条件分析,得到了其含水层主要补给、径流、排泄条件以及各含水层之间的水力联系。
According to the coal mining status of Tengnan coal mining area of Tengxian coalfield and the problem that need to be faced in coal mining,i. e.,Taiyuan formation coal seam is suffering a threaten of water inrushing from coal seam floor,the physical geography,stratigraphy,tectonic,hydrogeological conditions and characteristics were analyzed in Tengnan coal mining area,and it was divided into 3 grade-two units,8 grade- three hydrogeological units in accordance with the dividing basis. Through the hydrogeological condition analysis of hydrogeological units in Tengnan coal mining area,the conditions of aquifer recharge,runoff,discharge,and the connection between each aquifer were obtained.
