Develop Methods to Prevent and Control Spontaneous Combustion Associated With Mining and Subsidence
2003
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.

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.
Benefits of an Apiary at a Rehabilitation Site
2019
Desktop study based on literature, a stakeholder workshop and specialist consultation, assessing whether keeping bees on rehabilitating mine land pays, for closure teams weighing aftercare options.

The financial benefit of bees to a rehabilitating site could not be modelled with confidence, and a field trial to show direct benefit is hard to configure because so many variables affect rehabilitation. Apiaries suit sites where bee friendly plants are established, the return coming through honey yield rather than measured gains in biodiversity or ground cover, at low establishment cost.
