Análisis de ventilación de mina aplicado en la empresa GRUMINTOR S.A..

Abstract

This technical project was carried out with the objective of analyzing the ventilation system of the El Inca zone in the Grumintor 1 mine, belonging to the company GRUMINTOR S.A. For this purpose, an exhaustive bibliographic review of the fundamental concepts related to ventilation systems in subway mining was carried out. In addition, the cross sections of the mining workings that make up the El Inca zone were surveyed and monitoring stations were established for critical variables, such as air speed, gas concentration, dry and wet bulb temperatures, and relative humidity of the air. Based on the information collected, the required flow rate for level 2 was determined and the effective temperature and average humidity of the El Inca zone were obtained. Comparison of the results obtained with national safety standards allowed the performance of the ventilation system to be evaluated. To improve the understanding of the air flow dynamics in the study area, 3D modeling of the area was performed in the VentsimTM software, based on the topography obtained. In conclusion, the results of this study provide a critical and detailed evaluation of the ventilation system in the El Inca area, which contributes to ensure a healthy and safe working environment for mine workers. In addition, the recommendations provided can be used by the company to improve and optimize the ventilation system in the future, which would allow for efficient control of atmospheric contaminants and better management of thermal and humidity conditions in the work area.
