mudanças de tensões, e além de outros formalidades que asseguram estabilidade das rochas e diminuição de riscos de desplacamentos. Portanto, esta pesquisa foi de suma importância como aluno e futuro profissional no campo da mineração ou minas subterrâneas. Os conhecimentos foram valiosos para praticar os métodos, procedimentos e atuar com segurança na área que irei trabalhar.Respeitando as normas de conservação do solo e subsolo e extraindo o minérios de forma eficaz e segura.

under the first type of the stress state. Method is applicable in solving the rock mechanics problems. 1 INTRODUCTION Pillar design concerns matching pillar strength with pillar loading conditions to establish the dimensions that guarantee the pillar behavior as required. Despite structural simplicity and detailed knowledge of rock behavior obtained over the past years, pillar design has changed very little (Parker 1993). Consequently, the need of theoretical investigations and practical…

geotechnical to be dealing with the most abundant and one of the types of lower mechanical resistance that occur in final open pit’s. Catastrophic slope failures have occurred in iron ore mines leading to either fatalities or loss of production. The main cause is the stress concentration on the toe of slopes, which is basically composed of friable Hematite. To address this issue, geotechnical engineers leave a “buttress” of ore at the toe, leaving reserves. The design is based on…

propriedades mecânicas. vii ABSTRACT Methods of classifications of rock masses are good tools to assess and quantify the quality of a rock mass and assist in engineering projects in rock, such as excavations, opening galleries and tunnels, slope stability, and various other interventions that have as material, the rock. These methods quantify or describe in terms of numbers several characteristics of the rock mass. The main classification systems already developed as classification…
