There are several mines in this volcanic mountain, which have been quarried since the early medieval ages. This abandoned heavy and non-ferrous metal mine is about 340-m deep. Mine closure had become necessary due to environmental reasons, because the stored water was highly acidic. The goal of this paper is to present a complex rock engineering design for infilling the drift ways. First of all, a rock mass characterization was necessary for determining the different rock-mass parameters, along with the hydrogeological conditions. Secondly, the stability of the dam was verified by different lengths, applying a geotechnical software using the finite element method. The filling material (ash) originated from a nearby power plant. The dam was designed with a corresponding drainage system and drainage capacity. The filling ash was retained with geogrid-reinforced gabion walls.
