ABSTRACT
Purpose. Selection
of parameters and construction of a mathematical model for studying
the temperature regime in a mine working filled with methane-air mixture.
Methods. The
methods of thermodynamics and chemical kinetics were used in
the work.
Findings. As
a result of the research, a mathematical model of the self-heating
of a mine atmosphere containing methane was constructed, taking into account the evolution of its concentration
in a mine working.
Originality. A physico-mathematical
model has been built that makes it possible to investigate the dependence of temperature changes in a mine working on the chemical
and kinetic parameters of the gases filling
it, and also to take
into account the interaction of the mine
atmosphere with the walls of
the working.
Practical implications. The results obtained
can be useful for research on describing the temperature regime process in a mine working under appropriate external conditions and within a certain range of changes in the main
thermophysical parameters
of coals and rocks containing
it, and can be used
to predict fire hazard at great depths.
Keywords: mine atmosphere,
self-heating, methane, fire
