The use of fire radiative power observations to determine spontaneous combustion event activities associated with coal mining on the Mpumalanga Highveld
Coal mining is a significant activity on the Mpumalanga Highveld. One of the major air pollution issues associated with coal mining, is the spontaneous combustion of coal. There are no abatement technologies in place for such emissions, and typically long- and shortlived greenhouse gases, other gaseous pollutants and particulate matter are emitted by such events. For ambient air quality models to accurately capture the contribution of spontaneously combusted coal, it is necessary to determine the locations and durations of these burning events. Such information will also assist in explaining experimentally determined ambient air quality data. In this article, satellite fire radiative power (FRP) data from the Moderate Resolution Imaging Spectro-Radiometer (MODIS) was used to determine the locations and durations of spontaneously combusted coal within the Mpumalanga Highveld for January 2001 to December 2019. From the results it was concluded that five mining sites were prone to spontaneous combustion. These sites were all opencast mines situated on old bord and pillar mines. Two of these areas were actively burning for most of the 19-year study period. A relatively well-defined seasonal pattern was also observed, with combustion events being more prevalent during the winter months. Considering the active burning periods of the areas where spontaneous combustion were recorded, it is obvious that this is a major source of atmospheric pollutants on the Mpumalanga Highveld.

期刊介绍:
Clean Air Journal is the official publication of the National Association for Clean Air, a not-for-profit organisation. Clean Air Journal is a peer-reviewed journal for those interested in air quality, air quality management, and the impacts of air pollution relevant to Africa. The focus of the journal includes, but is not limited to: Impacts of human activities and natural processes on ambient air quality Air quality and climate change linkages Air pollution mitigation technologies and applications Matters of public policy regarding air quality management Measurement and analysis of ambient and indoor air pollution Atmospheric modelling application and development Atmospheric emissions Other topics on atmospheric physics or chemistry with particular relevance to Africa The scope of the journal is broad, but the core theme of the journal is air quality in Africa.
