Geotechnical evaluation of a waste rock dump from a limestone mine in south Brazil

This paper presents the geotechnical study and stability assessment of a Mining Waste Rock Dump (WRD) from Limestone Mine in city Dom Feliciano/Rio Grande do Sul (RS), south Brazil. A literature review is used to provide considerations on properties materials geometries adopted. These parameters were basis for evaluation performed realistic profiles WRD proposed expansion. The conclusions regarding are confirmed supported by quantitative classification methodology. results obtained demonstrate viability adopting an optimized geometry, with height 25 meters first level 15 second level. It concluded that methodology sequence steps adopted can be replicated other WRDs even serve as indication similar structures.
