Abstract
This report presents theoretical studies and experimental work dealing with the detection of dangerous roof and pillar conditions in underground mines through measurement of temperature differences on the surface of the mine opening. The theoretical work is directed at modeling the circumstances where a loose slab of rock might be detected. The experimental work provides input data for the theoretical models. The study produced mathematical models of heat flow in rock around coal mine openings. These models were verified by measurements in coal mines. The study provided data to support the Bureau's research in infrared detection of potential roof falls. The report substantiates that thermal difference techniques can be used effectively in well ventilated underground openings where there is a temperature difference between rock and the mine atmosphere.
