Determination of physical and chemical properties of coal and enclosed rock. Investigation of the propensity to spontaneous combustion of coal and mine rocks

UkrSGRI’s laboratories are authorized to conduct research on the physical and chemical properties of rocks and determine the parameters that cause the susceptibility to spontaneous combustion of coal, mine rocks and coal beneficiation waste.

Spontaneous combustion of coal, mine rocks and coal beneficiation wastes is an ability to spontaneously catch fire as a result of rock’s material low-temperature oxidation.

According to the Safety Rules in coal mines, the coal’s susceptibility to spontaneous combustion is established by specialized sectoral institutes and authorized organizations for all open layers and those that are being worked on within the minefield. If it is necessary (in case, if there are changes of mining geological and mining technical factors), but at least once every five years, the susceptibility to spontaneous combustion in mines must be checked.

The coal’s susceptibility to spontaneous combustion must be established in areas of geological disturbances of coal seams (except for anthracites) and basing on results of the analysis the appropriate measures should be developed, taking into account the recommendations given by a specialized sectoral institute or authorized organization to prevent endogenous fires.

Research results

The research result is a complex of parameters of physical and chemical coal’s properties, which allows to establish the level of susceptibility to spontaneous combustion of the studied coal or rock material. On the basis of the received data and according to fire code for the Ukrainian coal industry enterprises, the recommendations for rock ignition processes prevention are being developed accordig to the Instruction on prevention of spontaneous combustion and extinguishing.
