The international mining experience shows that increasing difficulty of extraction of mineral resources leads to their cost supplement. In this case, the methods to ensure occupational safety become more sophisticated. In particular, it is concerned with the required air supply in compliance with safety standards. The required level of occupational safety using modern automated control and monitoring systems supposes additional costs of implementation and operation. This article describes the unique experience of Belaruskali company in implementing modern automated mine ventilation system, providing new high level of occupational safety at the concurrent reduction in power consumption of ventilation. The scientific research into ventilation processes, introduction of method for dynamic ventilation control based on fresh air requirements in ventilation net sections per shift using automatic regulators, controlled recirculation and unique control algorithms has enabled reduction in energy consumption of mine ventilation systems by 50% of the initial level. At the present time, research and improvement of the dynamic mine ventilation control at Belaruskali company are in progress through testing of the control system of air supply directly to work areas based on real-time monitoring of mine air parameters and prediction of air quality and quantity variation through simulations of mine ventilation operation.
