摘要
研究区宏景塔一矿位于鄂尔多斯台向斜东胜隆起之东南边缘地带,构造简单,褶曲与断层均不发育,无岩浆活动。研究区矿井水主要来自新生界第四系松散岩类孔隙水,中生界碎屑岩类裂隙水。6-2煤层钻孔单位涌水量小于0.01 L/s·m,属于弱富水性;水质为HCO 3-Ca· Mg型及HCO 3-Na·Ca型水;矿化度0.26~0.46 g/L,属于矿化度很低的淡水。研究区水文地质类型为二类一型,即以裂隙含水层为主的水文地质条件简单的矿床。
The study area about Hongjingta coalmine loca-ted in the southeast edge of ordos platform syncline dongsheng uplift zone, the structure is simple, folds and faults are not de-veloped, and without magmatic activity. The mine water is main-ly from pore water of Cenozoic Quaternary loose rock, Mesozoic clastic rock fissure water. The 6-2 coal seam drilling unit inflow is less than 0. 01L/s·m, belongs to the weak water;water is the type of HCO 3 -Na·Ca and HCO 3 -Ca·Mg, salinity is 0. 26~0. 47g/L, belonging to the low salinity of freshwater. The types of hydrogeology in this area is the Ⅱof a type, that is the main of aquifer hydrogeological conditions of simple deposits.
