摘要：
This paper presents the results of an experimental study of flames propagating with an alternating-sign velocity in methane-air and coal dust-methane-air mixtures in a vertically located closed tube at coal dust concentrations of 0.10-0.42 kg/m(3). The results of the study can be useful for developing combustion models and assessing dynamic and thermal effects during combustion of methane-air-coal dust mixtures in coal mines.
