Análise Estatística e Influência do Tipo de Quebra dos Ensaios de Resistência à Compressão Uniaxial das Litologias que Compõem a Mina Ingá

maciço fundamental (UCS), geotécnicos realizados laboratório AngloGold ABSTRACT: Understanding rock mass parameters is crucial for geotechnical characterization. The rock mass strength, obtained from Uniaxial Compressive Strength (UCS), tests contributes to the rock mass characterization and is essential for guiding underground mines and open pits in terms of design parameters, numerical modeling and stope design. Due to it is importance, geomechanical tests are conducted in a Rock Mechanics internal laboratory of AngloGold Ashanti's operations in Crixás - Goiás - Brazil, where strength values from different rocks are obtained, forming a significant database. This study aims to determinate representative strength values, from each lithology from Ingá Mine, considering the disruptions that occur in the intact rock and in discontinuities, in addition to understanding the variables that can influence coefficient of variation, mean, boxplot and median, in order to eliminate outliers and define trends. Thus, a higher level of reliability is expected in geomechanical designs in terms of strength parameters.
