As coal mines get deeper, more mechanised and more productive the heat load on the ventilation system increases. In certain cases to the point where serious environmental problems may arise. To continue mining in these demanding conditions the sources of heat must be identified and evaluated so ameliorative measures may be taken. Due to the trend towards mining at greater rates and further from the shaft, mined coal on the conveyors is being recognised as a heat source of growing importance. This thesis describes its investigation.

Reviews of heat sources, psychrometry,heat stress indices and heat transfer are included to provide a background framework. The evaluation of the heat released by conveyed coal itself consists of theoretical treatment and laboratory investigations of heat transfer through broken coal. A model conveyor and its instrumentation constructed in a duct are described along with underground measurements at mines. The information obtained from theoretical, laboratory and on site investigations is analysed and summarised to provide a basis for future prediction.
