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 in statistical development of the general mine indicator of the number of fires per 1 million tons of production, in this study used the formation fire frequency coefficient, which characterizes the number of fires per 1 million tons of production from a given reservoir. The point is that the all-mine 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 ...
