||Mine ventilation techniques to solve microclimate problems underground
||Wettertechnische Massnahmen zur Bewältigung grubenklimatischer Probleme [in German]|
||5 Feb. 1981, Vol.117, No.3, p.124-131. Illus. 5 ref.
||Review of the causes of high ambient air temperature (air compression; heat emitted by rock, coal transported by conveyor, machines). Information on various methods for improving the microclimate: increasing ventilation flow, pneumatic stowing, ventilation method and air cooling. Description of the elements of an air cooling installation. Attempt to classify air-conditioning techniques in order of effectiveness. The techniques described are adequate for rock temperatures < 60°C, on condition that coal production does not exceed 1,500t/day (thin seam) or 3,000t/day (thick seam).
