Influence of mining and technical factors on the occurrence of endogenous fires in coal mines of Primorskugol Combine

Abstract

In contrast to the previously used mine-wide indicator of the number of fires per 1 million tons of production in statistical analyses, this study used the seam fire frequency coefficient, which characterizes the number of fires per 1 million tons of production from a given seam. The point is that the mine-wide indicator of the number of fires per 1 million tons of production correctly reflects the actual state, provided that the number of fires from the seams developed by the mine is distributed evenly over all seams. In practice, however, such a situation does not happen. ...
