Adequação da rampa principal na Mina Corgão da empresa Caltins Calcário Tocantins LTDA

Abstract

This research deals with the Main Ramp of the east cave of Corgão Mine at the company Caltins Calcário Tocantins Ltda. It presents the problem of reducing the number of downtime of the primary crusher for "lack of power" in vibratory feeder, which prevents the production of equipment generatins losses in the process of subsequent processing. This study aims to tailor the Main Ramp greide on the standards set forth in the literature to improve efficiency of traffic on the road and also deploy the prerogatives of Health and Safety at Work-based Regulatory Norm 22 and in Regulatory Norm of Mining 13. For that, it was used for both the literature review on the grounds of the theme, as well as field research in data. That done, we proceeded to collect data on the ramp as well as analysis. According to the investigation, it can be concluded that the adequacy of Main Ramp greide to 8%, provided an increase of 19.11% on average in the productivity of road trucks used for transportation. It is a caveat regarding the traffic of trucks when loaded because their time, in this regard, represent on average 41% of total time. Since it is the step that most influences the total cycle time, the gain of 26.33% was quite significant for the increase of productivity in the transportation.
