Formatted Abstract/Summary
In this paper we present a brief review of combustion issues associated with underground fires. Such fires are generally characterised by slow, heterogeneous combustion (or smouldering) of porous combustible materials, such as peat or coal. Due to specific characteristics of smouldering, such as low temperatures and small propagation velocities, underground fires are difficult to detect, especially in their initial stages. For the same reasons, estimation of the extent of the detected fire is problematic. Underground fires are also extremely difficult to extinct. Such fires can last for a very long period of time, posing a serious safety threat and having substantial adverse environmental and economic consequences. In this paper, we review current understanding of several major combustion issues in underground fires, which originated from the specifics of smouldering processes, including fire detection and measurements as well as some approaches to control and extinct the fire. We also review environmental and socioeconomic impact of underground fires. Limited number of publications on the issues associated with smouldering, in general, and underground fires, in particular, is available. As a result, our understanding of the phenomena involved is incomplete. Further research in the area is required.
