The article presents the results of the heat transfer analysis that is generated in an underground environment, specifically in coal mines. The objective is to observe the variability of the results, comparing mines with level access and inclined access; Another parameter of comparison has been the variation of the altitude at which the mines are located; The parameters of temperatures, air flow, relative humidity, air density, length of roads, quantity of explosive, number of miners, etc., have been collected in a coal mine located in the city of Cúcuta-Colombia. In order to speed up its use, it has used its own development software, which serves to model comfort and environmental quality underground.

El ruido generado por los equipos utilizados en operaciones y servicios mineros, es uno de los impactos que mayor número de incapacidades produce en los trabajadores que laboran en atmósferas subterráneas. Este estudio de evaluación del impacto ambiental producido por el ruido, se efectuó en varios frentes del sector denominado Inclinado 7, de la mina de carbón San José ubicada en el cerro Tasajero, Municipio de Cúcuta; allí, se realizó la medición del nivel sonoro continuo equivalente Leq del ruido ocupacional producido por equipos como: Ventiladores, electrobombas, martillos picadores (neumáticos) y perforadoras eléctricas. Se valoró la atenuación de este impacto, variando la distancia cada 5m. hasta llegar a 45m de la fuente. Con los resultados obtenidos se proponen medidas de gestión ambiental para el control del ruido y medidas preventivas y correctivas para mejorar el confort y la calidad ambiental bajo tierra.Palabras Clave: Ruido, impacto acústico, gestión ambiental, confort, calidad ambiental subterránea.

The research has been dedicated to the study of the calculation of the stresses and design conditions given by the safety factor of operation of the structural members of the mines that use wood as their main support material. Wood is a lightweight material, easily transportable and easily handled in ademe systems [1]. For this case, the structural member that is analyzed is the union between the column and the beam of the mine doors, known as the German door. For the development of the study, the geometry of standard doors commonly found in coal mining has been taken into account. The reason for the research on the proposed topic stems from the need to have a secure control over the structural sustainability of the mines, since the use and possible deterioration of the wood under operating conditions and in the mining environment is very important for human safety.
