| 摘 要： | 本数据集在1：50 000活鸡兔图幅内综合应用了遥感、地面调查、物探、钻探，以及水化学同位素等多种方法进行数据采集，共完成2期遥感数据解译800 km2，地面调查点377个，丰水期、枯水期地下水水位统测240点次，抽水试验10组，水体样品采集共计127组，水文地质钻探累计进尺600 m。本数据集细化了工作区内第四系孔隙含水层、白垩系洛河组孔隙-裂隙含水层富水等级，填补了侏罗系安定组、直罗组水文地质信息的空白；同时，加入了与采煤相关的次生环境地质要素，并首次将浅层含水层疏干区较为准确地勾画出来，还建立了采煤影响下的地下水的循环模式，突出了矿区水文地质调查的特色。本数据集为矿区水文地质调查工作的规划、部署与总结提供常态化支持，对保障国家能源安全、生态安全具有重要的现实意义。

| Abstract: | For this dataset of the 1:50 000 hydrogeological map of Huojitu, multiple methods such as remote sensing, surface survey, geophysical exploration, drilling exploration as well as hydrochemical isotope tests were applied for data acquisition. The remotely sensed data interpretation of 800 km2 area was successfully achieved in two phases, together with 377 surface survey points, 240 points of simultaneous-measurement of groundwater level during rain and dry seasons, 10 sets of pumping tests, 127 sets of water samples and 600 m of cumulative hydrogeological drilling footage. The level of water yield property of the Quaternary porous aquifer and the Cretaceous Luohe Formation porous fissure aquifer within the working area was refined in this dataset, filling the gap in hydrogeological information about the Jurassic Anding Formation and Zhiluo Formation. Meanwhile, secondary environmental geologic elements related to coal mining were added, and the unwatering zone of the shallow aquifer was successfully delineated for the first time. Furthermore, a groundwater circulation mode under the impact of coal mining was established, highlighting characteristics of hydrogeological survey in mine areas. This dataset provides normal support to plan, deploy and summarize hydrogeological survey in the mine areas, which is really important to guarantee national security in both energy resources and ecology. |
