SUMMARY:

Geotechnics is a discipline of great importance within civil activities, especially in mining, as it plays a crucial role in ensuring safe operational conditions and maintaining the economic viability of the enterprise. Understanding the lithologies present in the mine is essential for defining the ideal geometric parameters of slopes and thus optimizing the pit. To achieve this, it is necessary to conduct a geological-geotechnical investigation campaign with representative samples. The current study is being conducted in a pyrochlore mine located in the city of Araxá-MG, owned by Companhia Brasileira de Metalurgia e Mineração (CBMM) and CODEMIG (Companhia de Desenvolvimento Econômico de Minas Gerais), which are involved in the mining, mineral beneficiation, and metallurgical processes. The objective of the work is to develop a slope stability analysis study, i.e., to determine the best geometric conditions for short and long-term slopes. To achieve this, a resistance mapping and sampling campaign for physical characterization and shear strength (triaxial tests) were conducted for each lithology present in the mine. The results obtained from the tests will support the development of the stability study using the limit equilibrium method, with the Slide software from Rocscience. At the end of the work, the aim is to obtain a geometric sectorization map of the pit, reconciling safety and economic considerations for the operational development of the current and long-term pit
