Coal mining can seriously affect groundwater systems in aquifers that overlie the coal seam, especially in dry and water-stressed areas where protection of groundwater resources is very important. Through generalization of the hydrogeological conditions and analysis of the actual groundwater flow field in a confined weathered bedrock aquifer overlying the Shennan mining area in northern Shaanxi, a hydrogeological conceptual model and numerical groundwater flow model were established. FEFLOW finite element software was used to solve the model and dynamic groundwater data were used to validate it. The study area was hydrogeologically modeled by repeatedly adjusting the parameters. The model was then used to simulate the effect of mining on the overlying aquifer based on the mining plan for the next 5 years by adjusting the quantity of water discharged, the hydrogeological parameters of the upper water-bearing zone, the characteristics of the groundwater flow field, and the predicted water balance after 5 years. The results show that the maximum drawdown could be as high as 50 m (northeast of the Zhangjiamao Mine). A cone of depression centered on the Ningtiaota, Zhangjiamao, and Hongliulin mines will be formed that will influence more than 75% of the simulation area.

Hydrogeologisches Modell zur zukünftigen Grundwasserabsenkung infolge der Kohlegewinnung im Shennan Bergbaudistrikt, nördliches Shaanxi, China


Der Abbau von Kohle unter Grundwassersystemen in Aquiferen kann beträchtliche Auswirkungen haben, besonders in trockenen und wasserarmen Landschaften, in welchen der Schutz von Grundwasserressourcen sehr wichtig ist. Mittels einer Generalisierung der hydrogeologischen Randbedingungen und einer Analyse des derzeitigen Grundwasserfließfeldes in einem begrenzten Aquifer verwitterter Festgesteine über den Shennan Kohleflözen wurden ein hydrogeologisches konzeptuelles Modell und ein numerisches Grundwasserfließmodell erstellt. Digitalisierung und Berechnungen erfolgten in FEFLOW. Dynamische Grundwasserdaten wurden zur Validierung verwendet. Wiederholte Adjustierung der Parameter diente der Optimierung des Modelles. In der Folge wurde das Modell zur Simulation der Auswirkungen des Kohleabbaues nach dem Bergbauplan für die nächsten 5 Jahre eingesetzt, indem das geförderte Wasservolumen, die hydrogeologischen Parameter der wasserführenden Zone, die Charakteristika des Grundwasserfließfeldes und die Wasserbilanz nach 5 Jahren adjustiert wurden. Die Resultate zeigen, daß die maximale Absenkung 50 m erreichen könnte (nordöstlich der Zhangjiamao Mine). Ein Absenkungstrichter, welcher mehr als 75% des Untersuchungsgebietes betreffen wird, entsteht zentriert über den Minen Ningtiaota, Zhangjiamao und Hongliulin.




Modelo hidrogeológico para la predicción de agua subterránea en la región minera Shennan, China


La minería de carbón puede afectar seriamente los sistemas de aguas subterráneas en acuíferos que bordean la veta de carbón, especialmente en áreas secas y pobres en agua donde la protección de los recursos de aguas subterráneas es muy importante. Se establecieron un modelo conceptual hidrogeológico y un modelo numérico de flujo del agua subterránea a través de la generalización de las condiciones hidrogeológicas y el análisis del campo de flujo de aguas subterráneas en un acuífero confinado en un lecho de rocas, bordeando el área minera Shennan en el norte de Shaanxi. El software de elemento finito FEFLOW se usó para resolver el modelo y los datos dinámicos de aguas subterráneas fueron usados para validarlo. El área de estudio fue modelada hidrogeológicamente por sucesivos ajustes de los parámetros. El modelo fue posteriormente usado para simular el efecto de la minería sobre el acuífero basado en el plan de explotación minera para los próximos cinco años por ajuste de la cantidad de agua descargada, los parámetros hidrogeológicos de la zona superior del agua, las características del campo de flujo del agua subterránea y el balance de agua predicho para después de cinco años. Los resultados muestran que el máximo descenso podría ser de hasta 50 m (en el noroeste de la mina Zhangjiamao). Un cono de depresión centrado en las minas Ningtiaota, Zhangjiamao y Hongliulin se formará e influirá sobre más del 75% del área de la simulación.
