dc.description.abstract | This article presents the results of tests conducted on a measuring system for monitoring
changes in the distribution of temperature in a coal deposit during the heating and cooling phases,
and their correlation with the analysis of the concentration of gases. The tests were conducted on
five samples of hard coal collected in deposits mined in Poland. Measurements of the changes in
temperature and changes in gas concentration were conducted from the temperature of 35 to 300 C,
for the heating phase, and from 300 to 35 C, for the cooling phase. The percentage share of coal of
given temperatures was calculated. When comparing the percentage share for the same temperature
in the hot spot, for the heating and cooling phase, significant differences in the distribution of the
given percentages were observed. Changes in gas concentrations during heating and cooling were
analyzed and the dynamics of changes in gas concentrations were determined for the coals tested.
Changes in the values of fire hazard indices were analyzed. There were significant differences in
the concentration of gases and the values of fire hazard indices between the heating and the cooling | pl_PL |
