Fires in the Timber Lining of Mine Roadways: A Comparison of Data from Reduced-Scale and Large-Scale Experiments
The study of any type of combustion system by means of reduced-scale experiments presents problems, since a change in scale can produce major changes in the relative importance of the various physical processes occurring in the system. This paper is concerned with the development of scaling laws based on a simplified mathematical model of the development of fires in the timber linings of mine roadways. The application of these laws to data obtained in reduced-scale experiments predicted that, given a strong enough igniting souce, e.g. burning mineral oil, and a continuous timber lining, a previously unreported type of roadway fire could occur, in which all the oxygen in the ventilating air is consumed in the fire. A series of large-scale experiments confirmed this prediction. In addition, where detailed comparisons could be made the relationships between data from large-scale and experiments were in agreement with the formulated scaling laws. (Author)
