Explore how the implementation of Underground Ventilation works in a mining project

Implementing underground ventilation in a mining project requires consideration of several crucial points that begin with the mine design.

When developing this project, local geology is taken into account, the type of ore to be extracted, its distribution, the topography of the region, the number of people involved in the operation, and the equipment used, among other factors.

Based on this information, it is possible to determine the expected useful life of the mine and adequately size the underground ventilation system, ensuring an adequate supply of fresh air for the health and safety of workers at all stages of the exploration process.

Therefore, by having accurate information about the mine it is possible to evaluate and determine the best underground ventilation system, ensuring a safe working environment, with adequate circulation of fresh air and minimizing risks related to air quality and the presence of harmful gases or particles.

For an efficient implementation of underground ventilation, alignment between the teams involved is essential to ensure that the required resources are available. Mine staff must have access to all relevant information about exploration, and ventilation engineers must collaborate with operations planning engineers. It is important to emphasize that ventilation systems are designed for the most critical scenarios, but do not necessarily need to operate in these conditions all the time.

The determination of ventilation systems must be made according to your specific objectives and are subdivided into auxiliary ventilation or secondary ventilation and main ventilation commonly called exhaust fans.

Secondary or auxiliary ventilation

These are pieces of equipment commonly installed inside the mine and are smaller in size, which consequently blocks a smaller area in the gallery, but they play a crucial role in distributing air between the exploration galleries.
