Abstract	The hydrogeology of the Tangshan coal mine is extremely complicated. There are at least 20 major faults, with the offset exceeding 50 m. A large artificial lake was created where mining-induced subsidence occurred; it was filled with groundwater pumped from the adjacent aquifers near the coal seams. In addition, there are two nearby rivers that are also believed to have significant groundwater and surface water interactions. Both the river system and the large lake could be a potential threat to a new mining operation in the deep no. 5 coal seam. An in-situ hybrid packer system was designed to measure the thickness of the fracture zone and a 3-D hydrogeological model of the coal seam, associated aquifers, artificial lake, and surface water was established to simulate the groundwater flow field to evaluate the potential impact of induced fractures between the lake and the aquifers and coal seams. The results indicated that the lake has an insignificant impact on the aquifers and coal seams, though it does influence the shallow quaternary aquifer in the study area. Further study is suggested to monitor the groundwater and surface water interactions between the lake and the shallow aquifer system.Die Hydrogeologie des Tangshan Kohlebergwerk ist äußerst kompliziert. Es gibt mindestens 20 größere Verwerfungen mit einem Versatz von mehr als 50 m. Ein großer künstlicher See ist dort entstanden, wo es zu einer bergbaubedingten Absenkung gekommen ist. Er wurde mit Wasser aus den angrenzenden Grundwasserleiter in der Nähe der Kohleflöze gefüllt. Darüber hinaus gibt es zwei in der Nähe befindliche Flüsse, die vermutlich auch eine signifikante Wechselwirkung mit dem Grundwasser und Oberflächenwasser haben. Sowohl das Flusssystem und der große See könnten eine potenzielle Bedrohung für den geplanten Bergbau im Kohleflöz Nr. 5 sein. Ein In-situ-Hybriddichtungssystem wurde entwickelt um die Dicke der Bruchzone zu messen und ein hydrologisches 3D-Modell des Kohleflözes, verbunden mit den Grundwasserleitern und künstlichen Seen und Oberflächengewässer, zu erstellen. Daraus wurde ein Grundwasserströmungsfeld simuliert, um das Potenzial der entstandenen Brüche zwischen dem See, dem Grundwasserleiter und der Kohleflöze zu bewerten. Die Ergebnisse zeigten, dass der See einen unwesentlichen Einfluss auf die Grundwasserleiter und Kohleflöze hat. Jedoch gibt es einen Einfluss auf die flachen quartären Grundwasserleiter im Untersuchungsgebiet. Es werden weitere Studien vorgeschlagen, um die Wechselwirkungen zwischen Grund- und Oberflächenwasser, also zwischen dem See und dem flachen Grundwasserleitersystem zu untersuchen.La hidrogeología de la mina de carbón Tangshan es extremadamente complicada. Hay al menos 20 fallas mayores con desplazamientos que exceden los 50 m. Se creó un amplio lago artificial donde se produjo el hundimiento debido a la actividad minera; el mismo fue llenado con agua subterránea bombeada desde los acuíferos adyacentes cercanos a las vetas de carbon. Además, hay dos ríos muy cercanos que se cree pueden tener interacciones con las aguas subterráneas y superficiales. Tanto el sistema de ríos como el lago podrían ser una amenaza potencial para la nueva operación minera en la veta de carbón n° 5. Se utilizó un sistema híbrido para medir in situ el espesor de la zona de fractura y se estableció un modelo hidrogeológico 3D de la veta de carbón, acuíferos asociados, lago artificial y agua superficial para simular el flujo de agua subterránea y evaluar el potencial impacto de fracturas inducidas entre el lago y los acuíferos y las vetas de carbón. Los resultados indicaron que el lago no tiene impacto significativo sobre los acuíferos y las vetas de carbón, aunque tiene influencia sobre el acuífero cuaternario de poca profundidad que está en el área de estudio. Se necesitan nuevos estudios para monitorear las interacciones entre aguas subterráneas y superficiales y entre el lago y el sistema acuífero de poca profundidad.唐山矿水文地质条件极其复杂,至少有20条以上主要断层,总断距超过50米。该区因长期开采形成沉陷区,引入煤层相邻含水层的水进入该沉陷区形成人工湖。另外,附近不远处的两条河流对地下水和地表水的交换有重要影响。由于河流和人工湖的双重影响,给新开采的5号煤层带来潜在的突水威胁。导高测量仪用来测量冒裂带的厚度,同时结合含水层、人工湖、地表水等信息建立3-D水文地质模型确立地下水流场,评价人工湖、含水层以及煤层间导高裂隙带来的潜在影响。结果显示:人工湖对含水层和煤层产生重大影响,尽管在研究区域仅对浅层第四系含水层有影响。下一步的研究重点应该着重监测人工湖和浅部含水层的交换规律。
