Resumo: Heat generation in underground mines is a factor of extreme influence on the production, safety and comfort of workers. This article aims to analyze heat sources in an underground mine and propose, as one of the alternatives to improve ventilation conditions, replace the diesel fleet with electric. The case study shows that this is the second source of heat, being the first autocompression, the second diesel equipment and the third are the fans. The heat emitted by the rock then stabilizes a certain time having no significance in the temperature in the year of 2019, but in 2026 it will be a significant heat source. This evaluation was carried out in a gold mine near Belo Horizonte, capital of the State of Minas Gerais using the software Ventsim.  In the study, sensitive heat and latent heat would be reduced by about 56% and 80%, respectively, if the change is made. This reduction in the heat generated by the system may improve working conditions because of lower temperature and gas concentration, which reflect on the safety conditions for higher worker's efficiency.

Este artículo tiene como objetivo analizar las fuentes de calor en una mina subterránea y proponer, como una de las alternativas para mejorar las condiciones de ventilación, sustituir el parque de motores diesel por eléctrico. El estudio de caso muestra que esta es la segunda fuente de calor, siendo la primera la autocompresión, la segunda los equipos diésel y la tercera son los ventiladores. El calor emitido por la roca luego se estabiliza en un cierto tiempo sin tener importancia en la temperatura en el año de 2019, pero en 2026 será una fuente de calor importante. Esta evaluación se realizó en una mina de oro cerca de Belo Horizonte, capital del Estado de Minas Gerais, utilizando el software Ventsim. En el estudio, el calor sensible y el calor latente se reducirían en aproximadamente un 56 % y un 80 %, respectivamente, si se realiza el cambio. Esta reducción en el calor generado por el sistema puede mejorar las condiciones de trabajo debido a la menor temperatura y concentración de gases, lo que se refleja en las condiciones de seguridad para una mayor eficiencia del trabajador.A geração de calor em minas subterrâneas é um fator de extrema influência na produção, segurança e conforto dos trabalhadores. Este artigo tem como objetivo analisar fontes de calor em uma mina subterrânea e propor, como uma das alternativas para melhorar as condições de ventilação, substituir a frota a diesel por elétrica. O estudo de caso mostra que esta é a segunda fonte de calor, sendo a primeira a autocompressão, a segunda os equipamentos a diesel e a terceira são os ventiladores. O calor emitido pela rocha então se estabiliza por um certo tempo não tendo significância na temperatura no ano de 2019, mas em 2026 será uma fonte de calor significativa. Esta avaliação foi realizada em uma mina de ouro próxima a Belo Horizonte, capital do Estado de Minas Gerais, utilizando o software Ventsim. No estudo, o calor sensível e o calor latente seriam reduzidos em cerca de 56% e 80%, respectivamente, se a alteração fosse feita. Essa redução do calor gerado pelo sistema pode melhorar as condições de trabalho devido à menor temperatura e concentração de gases, o que reflete nas condições de segurança para maior rendimento do trabalhador.Research, Society and Development2023-01-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3965110.33448/rsd-v12i2.39651Research, Society and Development; Vol. 12 No. 2; e0812239651Research, Society and Development; Vol. 12 Núm. 2; e0812239651Research, Society and Development; v. 12 n. 2; e08122396512525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/39651/32644Copyright (c) 2023 Leandro de Vilhena Costa; José Margarida da Silvahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCosta, Leandro de Vilhena Silva, José Margarida da 2023-02-14T20:07:52Zoai:ojs.pkp.sfu.ca:article/39651Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2023-02-14T20:07:52Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
