Abstract. Experimental results of gas release and volatile composition dynamics under thermal impact are presented in this article with the purpose to develop of technogeneous deposits of coal slimes and low-grade coals .

Laboratory method included heating of  coal-contained materials and their binary mixtures without air access and defining of gas phase volume and composition depending on the process duration and temperature. Total amount of volatiles generated by a certain time point is calculated with taking into account isothermal and nonisothermal conditions, heating rate and kinetic parameters. Causes of varied content of gaseous components are analyzed.

The findings can be applied for specifying parameters when designing  a thermal processes model for coal-contained materials processing.

Keywords: thermal impact, coal-contained materials, gas release, volatiles composition, gas phase.
