If this sort of data were available, the feasibility of controlling the duty of the primary fans could be determined. This analysis, to some extent, has also assumed that all areas need to be ventilated to a certain degree; consequently, a concurrent activity/equipment movement and auxiliary fan operation benchmark data set would also be beneficial. Furthermore, the quantities assigned to production activities have been based upon the tonnage. The temperature investigations have shown to some degree that conditions in the general travel areas of the mine are independent of activity.

Consequently, ore dumping may only need the lowest level of control, whereas backfilling may need the highest level of on/off control. 23 Copyright © 2006 Taylor & Francis Group plc, London, UK COST SAVINGS WITH VOD Table 4.

Heating is controlled by temperature sensors and thus works automatically. 2 Current ventilation status The ventilation situation of the standby mode was investigated at a surveying visit. The fresh air shaft ivn1 was functioning well. The amount of fresh air arriving to the level +700 m was about 40 m3 /s. On the other hand, the fresh air shaft ivn2 had some problems. Three of the shaft fans were not functioning, and there was a cave-in in the shaft, which partly had plugged the shaft at the level +490 m.
