Abstract
The objective of creating safe working conditions in coal mines can be classified as very challenging and multifactorial. The normative document base in the field of mining safety must be constantly updated and revised, taking into account the results of research conducted by research organizations. Issues related to gas and fire safety issues, gas- and geo-dynamic phenomena, rock pressure are particularly relevant.
The article considers one of the aspects of safe working conditions, namely, fire safety. The analysis of methods for predicting endogenous processes has been performed, the results of experiments aimed at determining the criterion signs of self-heating stages in coal mines of the Karaganda coal basin are presented.
Keywords
Fire safety, Endogenous fire, Chemical activity of coals, Low-temperature oxidation, Self-ignition, Unsaturated hydrocarbons, Mined-out space, Isolated area.
