2水文地质研究现状
自二十世纪七十年代起，中国煤田地质总局水文地质局、河北省地矿局、水利部门开展并完成了黑龙洞泉域岩溶裂隙地下水勘探评价，邯邢水文地质南单元岩溶地下水研究及集中式开采所带来的水环境影响预测、邯邢煤矿区矿床水环境问题调查评价，以及全国水资源一次、二次评价，水资源区划及中长期供水规划，地下水动态观测报告。较大的煤矿为了防治水进行过矿床水文地质勘探研究工作。查明了黑龙洞泉域岩溶裂隙地下水系统的边界，地下水补径排条件及水资源量，地下水动态变化特征，以及地下水及煤、铁矿矿开采对岩溶地下水系统的影响等。
3地质水文地质概况
黑龙洞泉域位于新华夏构造体系第三隆起带太行山东侧，地层分区属于华北地层大区—晋冀鲁豫地层区。受新华夏构造体系控制，地层走向北东—北北东向，倾向南东，倾角10°-25°。区内地层出露较全，矿区地层由老至新为：太古界、元古界、寒武系、奥陶系、石炭系、二叠系、三叠系以及新生界第三系、第四系。走向大致为NE倾向SE，倾角10-20°。 该泉域为一独立封闭程度较高的全排型岩溶水系统。北界为震旦系隔水边界；西界南段为涉县—长亭阻水断层，北段为震旦系隔水边界；东界为奥灰埋深标高-800米和阻水断层边界；南界为地下分水岭边界。泉域面积2404km，寒武系、奥陶系裸露面积1262 km，多年平均资源量11.36m/s。
按断层岩性、含水介质空间类型大体可分为三大含水岩系。第四系松散岩类孔隙含水岩系含水层薄，富水性差；石炭系、二叠系碎屑岩夹碳酸盐岩裂隙含水岩系富水性弱—中等；寒武奥陶系岩溶裂隙含水岩系，特别中奥陶岩溶裂隙发育，补给径流条件好，富水性强，是本区主要含水层。

流区水化学类型主要为HCO3·SO4-Ca·Mg、HCO3·Cl-NaMg、HCO3·Cl-Ca、Cl·SO4-Na·Ca型，矿化度在600—1100mg/l。
3. The situation of geological and hydrogeological
Hei longdong spring area are located in the third uplift belt of Neocathaysian structural system adjacent ed to the west of Taihang Mountain, and the stratigraphic subregion belong to the strate of north china and Shanxi-hebei-shandong-henan area.under the control of Neocathaysian structural system,formed a NE-NNE strike,dip SE,dip angle 10-25°stratigraphic unit. Strata exposed over the whole region,and from the old to young in the mining area are: Archaeozoic, Proterozoic, Cambrian, Ordovician, Carboniferous, Dyas,Triassic,Tertiary and quaternary. NE strike,dip SE,dip angle 10-20°.
The spring area is a independent karst water system which has a higher sealing degree and a completely drains,The northern confining boundary is Sinian; The southern section of the west boundary is the SheXian – ChangTing water blocking faults, northern confining boundary is Sinian;the eastern boundary are the Ordovician limestone which buried deep level is -800m,and the water blocking faults;the sounthern boundary is underground watershed.The spring area is 2404km2,the area of outcrop of Cambrian and Ordovician are 1262km2,and the average for many years of the resource is 11.36m/s.
According to the fault lithology and the space types of the aquifer medium it can be divided into three main water-bearing rock series.Quaternary loose rocks water-bearing rock series which is thin and poor; Carboniferous and Dyas clastic rock nip carbonate fissure water-bearing rock series which is medium; Cambrian and Ordovician karst fissure water-bearing rock series, especially the Middle Ordovician which has multiple fractures,better rechargeand water-abundance, have been the major water-bearing stratum in this area. 3
