Our paper is devoted to the reclamation of the environment degraded by mining activities. Specifically, it is about an andesite quarry in Vihorlat mountain range. The results show that stabilization of slopes is important from the point of view of technical reclamation of the environment. For mining purposes, the slope angle was defined as 60°. During the opening, preparation and realization of the extraction, the parameters of the operation were influenced by the cohesion in the rock mass c = 14.29 MPa, bulk mass γ = 2.646 kg, m-3 and internal friction angle φ = 50-75°. As part of the reclamation of the degraded area, it is also necessary to perform biochemical reclamation to increase the biodiversity of the area. One possibility is to build a water tank with a bottom area of 8,700 m2. The project results in the following dam parameters: 26 m heel thickness, 5 m thickness on the top, 12 m width, 11 m height, water slope angle 42° and air slope angle 51°. The possibilities of the reclaimed environment of the Zemplínske Hámre quarry are various.
