The article presents summarising information of solving issue of lignite tendency toward self-ignition (oxireactivity). A procedure of solving laboratory research of four lignite samples will be gradually described. But at first attention is paid to the description of the studied lignite samples and to flow calorimetry technique which was used as a main experimental methodology. The article describes so a part of research carried out in fame of complex long-term measurements on lignite dumps.

Keywords: coal self-ignition, pulse calorimetry, oxireactivity, adiabatic oxidation, tendency to self-ignition
