Develop Methods to Prevent and Control Spontaneous Combustion Associated With Mining and Subsidence
Fourth year of work at South African collieries, using borehole and infrared temperature monitoring, moisture testing and sealing trials, with control measures for opencast and underground operations.
by Dr. Nehar Eroglu & Conri Moolman | March 2003
No standard technique for predicting, controlling or extinguishing spontaneous combustion emerged, and the methods in use proved expensive and not routinely successful. Because every mine differs, the work sets out a sequence of locating the fire, assessing the risk, choosing a strategy and method, then monitoring it. Separate control measures are given for old workings, exposed coal and spoil heaps.
