AbstractRecent studies indicate that, of the total electrical energy consumed underground in Canadian mines, the largest portion is consumed by the ventilation systems. Further, it has been apparent for a number of years that substantial savings (30 to 35%) in ventilation energy costs can be achieved by the introduction of monitoring and mine ventilation systems. In spite of this, the subject is relatively undeveloped from both the theoretical and practical points of view.
However, recent advances in sensor/computer technology now permit the automation of ventilation in underground mines. At present, a few limited systems designed to reduce ventilation on demand by fan control, have been installed in underground mines to achieve energy saving benefits alone.
The automated control of ventilation systems is best achieved by making use of real-time airborne contaminant concentration measurements. In this fashion, air is being supplied on an as needed basis which results in a healthy work environment as well as cost savings. This system can also supply up to the minute information in emergency situations (for example, fire detection, warning and escape) and help with production problems such as post-blast re-entry times.
During the last five years, CANMET has been systematically developing elements of an overall plan designed to achieve both the potential energy savings, and the suitable mine environments associated with automated ventilation control systems.
