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.

No single global standard governs refuge bay design, and the collieries surveyed differ widely in construction, location, equipment and operating practice, which made ranking them impractical. Areas needing attention were identified in design, construction and maintenance of the facilities that keep people alive until rescue, drawn against local law and overseas practice.

Dolerite intrusion mechanisms and their metamorphic effect on coal were examined across four collieries in the south eastern Witbank Coalfield. In decreasing order of importance, intrusions cut safety by raising the risk of roof, pillar and floor failure, raise mining costs, reduce saleable tonnage, and increase waste generation and environmental risk.
