Avaliação do cálculo do volume de minério grafita em ocorrência no sul da Bahia

Abstract

This study aimed to evaluate the prospecting and cubing of mineral occurrences, which are extremely important phases for the success of a mining project. Defining an assertive and adequate survey grid is essential to obtain the best information on the depth and volume of the ore, as well as to obtain more precise information on the ore grades at each point surveyed. To reach the moment of defining the adequate survey grid in a project, it is necessary to strictly follow some steps in the mineral research work, which include a prior reconnaissance of the researched area and a bibliographic survey looking for published works and geological maps on the target research area. The maximum amount of information found in this phase is essential to serve as a theoretical basis for the professional to conduct the work. The field stages involve the complete geological mapping of the area, which involves collecting information on the geological formation of the area, descriptions, obtaining geological measurements and collecting samples from outcrops. Mapping services may require some additional work such as opening wells, trenches or some type of auger survey. Therefore, all this information is extremely important to define a drilling network that is truly efficient to successfully calculate the volume of the occurrence and prove the viability of the mineral project.
