Abstract	The complex hydrogeological conditions of the Gaoyang Iron Mine area were responsible for two water inrush accidents that occurred during tunneling at the horizontal level of −245 m on August 17, 2000 and August 29, 2004. Borehole computerized tomography in the key areas of the mine and groundwater level monitoring data were used to identify the main underground hydraulic channel and its characteristics. A grout curtain, designed and emplaced based on the results of this study, was highly effective in reducing the groundwater levels in the mine area and amount of water pumped from the mine.Die komplexen hydrogeologischen Bedingungen der Gaoyang Eisenerzmine waren der Grund für zwei Fälle von Wassereinbrüchen, die beim Stollenvortrieb am 17. August 2000 und 29. August 2004 in der Sohle bei −245 m auftraten. Zur Erfassung der Hydraulik und insbesondere der unterirdischen Fließwege des Wassers werden Grundwassermonitoringdaten und im zentralen Bereich der Mine rechnergestützte Borlochtomographie eingesetzt. Der Einsatz der Schleierverpressung, dessen Einlagerung und Zusammensetzung auf dieser Studie basiert, erwies sich als sehr effektiv bei der Senkung der Grundwasserstände bei gleichzeitiger Senkung des abgepumpten Wasservolumens im Bereich der Mine.Las complejas condiciones hidrogeológicas del área de la mina de hierro Gaoyang fueron responsables de dos accidentes de irrupción de agua que ocurrieron durante la construcción de túneles en el nivel horizontal a −245 m en Agosto 17, 2000 y Agosto 29, 2004. Tomografía computarizada de los pozos en las áreas claves de la mina y datos monitoreados del nivel de agua subterránea fueron usados para identificar el principal canal hidráulico subterráneo y sus características. Una barrera de lechada de cemento, diseñada y emplazada de acuerdo a los resultados de este estudio, fue altamente efectiva en reducir los niveles de agua subterránea en el área de la mina y la cantidad de agua bombeada desde la mina.复杂的水文地质条件是高阳铁矿 − 245水平发生2000年8月17日和2004年8月29日两次坑道突水的重要原因。研究采用孔内计算机层析扫描(CT)和水位监测相结合的方法识别主要突水通道及其特征,基于突水通道识别进行围幕注浆设计与施工,有效地降低了开采区地下水位、减少了矿井疏水量。.
