LANDFILL STABILIZATION IN OPEN PIT MINE OF BOGATA, BRASOV COUNTY

Abstract

The open mine of Bogata’s aim is the exploitation of basalt resulting from the Quaternary volcanism of Racoş. The current surface of landfills is irregular, as a result of the movements of material that have occurred in recent years, due to the exceeding of the natural slope angle of the material. Based on the results of geotechnical investigtions we have proposed a reshape of the landfill. Analysis by finite element method has highlighted a dangerous accumulation of horizontal efforts on the western area. Therefore we considered necessary to add a support element consisting of a body of reinforced soil with geosynthetic materials
