15 aqueous solutions of additives to inhibit the self-heating of coal were studied with respect to differentiate between physical and chemical types of their interaction with coal.Using SETARAM C80 calorimeter, immersing heats of the coal by additives solutions were determined. Method of the pulse flow calorimetry was then applied to quantify change in oxyreactivityof the coal treated by the additives. Two types of bituminous coals were investigated. As possible inhibitors, both inorganic (chlorides, sulfates, nitrates,phosphates,sulphites)of the coal treated by the additives. Two types of bituminous coals were investigated. As possible inhibitors, both inorganic (chlorides, sulfates, nitrates,phosphates,sulphites)

Method of the pulse flow calorimetry was then applied to quantify change in oxyreactivityof the coal treated by the additives. Two types of bituminous coals were investigated. As possible inhibitors, both inorganic (chlorides, sulfates, nitrates,phosphates,sulphites)and organic substances were examined, all being prepared as 10% aqueous solutions.
