Non-metallic mining quarries have instability problems in their short, medium and long-term operation phases. The instability they present is a result of many triggers factors, such as earthquakes, ground movements and others that can be noticed its influence during the tillage activities. The control of instability triggers factors can be achieved through the determination of global and local pit security, which would avoid economy and human lives losses during the project’s lifetime. This Academic Work develops the analysis of stability for the slopes of two pits of the quarry called “La Tormenta”, which is located in Palca District, Province of Tarma, and Department of Junín and belongs to Las Camelias S.A. Mining. This company extract talc, which is non-metallic mineral that is used as an aggregate in ceramic Industry. This research is part of the mining plan, which is presented to the Regional Government of Energy and Mines, this document is required to give the final approval before mining activities in non-metallic quarries start. Therefore, this academic work is governed by current National Regulations that are directly or indirectly related to this project. The aim of this research is to review and elaborate previous studies like topographic, hydrological, geological and seismic risks. The elaboration of these studies was the basis of the approach of the geotechnical model; because it allowed us to know the local geography and geology, the runoff of the area and seismic risk. Knowing all the aspects listed above assure better management of the environmental conditions of the geotechnical model. To conclude, the geological model considered the laboratory results for the properties of the rock, failure criteria such as the generalized of Hoek-Brown or Mohr –Coulomb and the optimal geometries for mining proposed by the geology area. The analysis was developed in statics and pseudo-static conditions using limit equilibrium method, with Slide 6.0 software. Results bring us safety factors above the minimum required by national regulations.
