The main objective of the research paper entitled "Optimization of the Ventilation System at the Sheridan Mining Explorations El Combe E.I.R.L. mine was to determine the degree of improvement of the ventilation system when optimized, in order to address the excessive accumulation of gases at the Sheridan Mine. The experimental, descriptive comparative methodology was used, taking as a population all the workings of the Sheridan mine and as the most representative sample the entire Sheridan Ramp, which is the only main access that goes from the mine mouth to the deepest area of the mine with approximately 350 meters. Sheridan is characterized by having blind operations, at first, they used a forced ventilation with a 15,000 cfm (424.8 m3/min) fan installed at the mine entrance with a 26” sleeve extended 300 meters along the main Ramp, which generated recirculation and long times of gas evacuation, generating the accumulation of these throughout the main ramp and nearby works. In this research, the ventilation survey was carried out, followed by the calculation of the total air requirement according to personnel, equipment and leaks, which was 14531.3 cfm (411.5 m3/min). To cover the requirement, it was determined that natural ventilation would be the most economical option with the connection of a chimney to the surface due to pressure changes (3930.0 USD), increasing the air requirement from 69% to 88% which would generate flows continuous in the work. Likewise, only auxiliary ventilation should be used to channel flows and evacuate blast gases from 1:48 to 0:51 hours (46.9%) and regulate entry times. Finally, it is concluded that it observes a significant reduction of 59.9% in the accumulation of gases in the ventilation system of the Sheridan Mine when optimizing the system.
