Numerical analysis of effects of an open-pit coal mine to groundwater [PDF]

International Journal of Engineering and Management Sciences, 2019
In this study we investigated the hydrogeological problems of an open-pit brown coal mine in the Borsod coal basin with Processing Modflow software. The coal mine is located in the valley of the Sajó-river with high transmissivity overburden layer where the traditional dewatering solutions were not encouraging due to inrush risks and low cost ...
