Abstract:

Mines can ill afford to neglect their ventilation systems as they can consume 30-4% of the electricity used in underground mines. In addition, mines can incur significant heating costs and cooling costs depending on their geographic location. For mines to be their most cost efficient they must embrace existing and emerging technology to optimize the use of their air; namely, maximizing its work in diluting and removing pollutants, limiting leakage, and avoiding the unnecessary loss of costly fan pressure. In its simplest form the cost of running a fan is proportional to the quantity cubed; therefore, reducing current ventilation demands on limiting increases brought on by more stringent legislation can produce very significant cost savings. In this paper for the importance of ventilation in safety, the most efforts are to prove the application of an air management system based on ventilation-on-demand, air quality and energy management principles. At the heart of the system is the integration of a control and monitoring system, a mine ventilation modeling and simulation system, and an expert system. With such an air management system, the mines will have: A simple to use simulator to design and test ventilation scenarios. Remote controls for fans, doors and regulators to implement changes. Real time monitoring of airflow, pollutant concentrations, and both vehicle identify and location to show whether changes are necessary. Ventilation-on-demand based on vehicle location and air quality. When these capabilities are available, a mine's ventilation system can be operated at a minimum cost.
