The Department of Mining Aerology performs scientific and research works for mining and non-mining entities in the field of ventilation, air-conditioning and fire hazard prevention. The Laboratory of Coal Spontaneous Combustion specializes  in forecasting, assessing and fighting fire hazard in hard coal mines based on constant monitoring of the mine atmosphere in the areas of exploited longwalls. Comprehensive chromatographic analysis of mine air samples and the possibility of trace determination of such gases as acetylene, ethylene, propylene, hydrogen, carbon monoxide and isotopes of hydrogen and oxygen allows an objective evaluation of the development of the self-heating process in coal mines. The Laboratory has fully automated and modern measuring equipment necessary for fast and very precise determination of the selected components of mine air as well as for performing tests on coals. The equipment consists of 10 gas chromatographic stations, 2 gas chromatographic/mass spectrometric stations, sorption station and several calorimetric stations, each of them equipped with specialized software for recording and processing the results of performed analysis.
