NOUFERROUS METALLURGICAL EQUIPMENT

This study conducts an in-depth analysis on the current operational status of the underground ventilation system in a high-altitude metal mine, identifying the characteristics of oxygen supply and temperature maintenance in high-altitude underground environments. Based on the demand-based ventilation theory, a ventilation system integrating remote fan control and demand-based ventilation functions was developed. This system enables remote and precise control of underground ventilation from the surface, along with demand-based ventilation adjustments, significantly improving ventilation efficiency and energy efficiency. Measured data from multiple workstations were analyzed using an extension model, and the evaluation results showed good consistency with the actual conditions, proving the feasibility of the proposed method. After the system was implemented, power consumption was reduced by 15%, and the effective ventilation rate was consistently maintained above 85%. The study provides a strong theoretical foundation and practical reference for the design and optimization of ventilation systems in similar mines.
