摘　　要：二_(1)煤层为张得矿区全区可采煤层,通过对矿区水文地质边界条件分析、主要含水层和断层带的水文地质特征综合分析,认为二_(1)煤层顶板砂岩裂隙水为顶板直接充水水源,太原组上段石灰岩岩溶裂隙水为煤层底板的直接充水水源,太原组下段石灰岩岩溶裂隙水和寒武系白云质灰岩岩溶裂隙水为底板的间接充水水源;地下水是其主要充水水源,断层是主要充水通道;太原组上段石灰岩岩溶裂隙水是底板突水最大隐患,是未来矿井开采突水预防主要对象。No.Ⅱ_(1) coal seam is the minable coal seam in Zhangde mining area,Through the analysis of the hydrogeologi⁃cal boundary conditions of the mining area,the comprehensive analysis of the hydrogeological characteristics of the main aqui⁃fers and fault zones,It is considered that the fracture water of sandstone in the roof of No.Ⅱ_(1) coal seam is the direct water fill⁃ing source of the roof,the limestone karst fracture water in the upper part of Taiyuan formation is the direct water filling source of the coal seam floor,and the limestone karst fracture water in the lower part of Taiyuan Formation and the dolomitic limestone karst fracture water in Cambrian are the indirect water filling sources of the floor;Groundwater is the main water source and fault is the main channel;the karst fissure water of limestone in the upper part of Taiyuan formation is the biggest hidden dan⁃ger of water inrush from the floor and the main object of water inrush prevention in future mining.
