Modelamento do desmonte com explosivos em rochas graníticas visando a otimização dos processos de cominuição utilizando a metodologia KUZ-RAM

Abstract

Explosive rock blasting modeling requires input parameters such as rock geology and geotechnical data and drilling and blasting to perform simulations to obtain the ROM particle size distribution. Simulations are critical for obtaining scenarios and greater reliability in decision making. The fragmentation model can be commonly used to obtain the result of fragmentation in the beneficiation plant in the design phase or in an operation and to help in deciding which equipment and processes will best suit the rock type and mineral asset. In this work simulations were conducted aiming to reduce the top size and consequently the reduction of the stop time due to cages and obstruction in the primary crushing. Taboca Mining is a mature mining operation and this work brought results that guided the operation as to the means to obtain better results in the comminution stages.
