Simulación del sistema de ventilación en la empresa GRUMINTOR S.A.

Abstract

The present study aimed to simulate the ventilation system of the Grumintor 3 mine of the company GRUMINTOR S.A., located in the Camilo Ponce Enríquez canton of Azuay province, therefore, it was necessary to collect in situ information of the topography, sectional dimensions and thermohygrometric conditions of the underground workings, Afterwards, the main and secondary ventilation system of the mine was simulated with the use of Ventsim and Vuma software applied for underground mine ventilation based on 3D modeling. Finally, based on the current regulations on worker safety and health in the mining area, it was verified that the conditions mentioned above are within the permissible parameters for underground mining activities. As a result, it was found that the thermal conditions are adequate; however, there is a very humid environment. Finally, regarding the speed of air currents are moderately adequate and therefore, the lack of air flow to meet the requirements; for this reason, it was recommended the implementation of a fan in the mine mouth of pedestrian entrance to supply the missing flow necessary to meet the requirement and the construction of a chimney near the exploration front for better circulation of contaminated air currents to improve the mining atmosphere and air flow velocity.
