Planejamento de curto prazo para uma pedreira de calcário - estudo de caso.

Abstract

This study aims to establish a methodology for short-term planning in a limestone quarry. The main objective is to reduce the standard deviation in the concentration of CaC03, Si02, Fe203 and A1203 in the ROM (Run of Mine). These are the components of the basic raw materials (limestone and clay) for the manufacture of clinker. This type of quality control results on mine reduced costs. This occurs by the elimination of actions to correct quimical quality after crashing. In consequence there is also a better use of the reserves. Many simulations have been done using a specific kind of mining software for mine sequencing. The technique used can be named of "parameters estacionarized".
