Mine Ventilation

Mine ventilation is a key pillar of safety and operational efficiency in any underground site. At CGM Expert, we offer a complete range of specialized mine ventilation services to ensure a safe, compliant, and optimized working environment.

Our services include:

Analysis and diagnosis of existing systems
→ Assessment of current performance, identification of weak points, field surveys, and airflow modeling.
→ Complete ventilation survey including airflow volumes, pressure, contaminant dilution, and temperature.
→ On-demand maintenance and servicing of the ventilation system.

Design of new ventilation systems
→ Determination of fresh air needs based on equipment list, planned production and development, and underground infrastructure.
→ Sizing and selection of ventilation equipment (main fans, auxiliary fans, regulators, doors, ducting, etc.).
→ Integration of safety, energy efficiency, ventilation on demand, and cost (MTO) criteria.

Ventilation optimization and engineering
→ Reduction of energy costs by revising ventilation strategies (ventilation on demand, automation, zoning).
→ Continuous improvement recommendations to enhance system efficiency without compromising safety.

Digital modeling (using Ventsim, CFD, and others)
→ Detailed simulations of airflow and contaminants, including normal and emergency scenarios.
→ Decision-making tools for engineers and site managers.
→ Ventilation modeling aligned with long-term mine planning (LOM).

Operational support and field assistance
→ Deployment of technicians or engineers on-site to supervise implementation or conduct follow-ups.
→ Assistance in case of non-compliance with applicable standards (e.g., CNESST).
