PROBLEM OF SPONTANEOUS FIRES AND SELF-IGNITION PREDICTION IN THE MOSCOW COAL BASIN

In focus of the article is the investigation and prediction of spontaneous ignition of coal in the Moscow Basin. The investigation procedure is based on the coal bed data obtained at the stage of geological exploration. As a result of studying geological structure of a coal bed, physicochemical analysis and statistics on spontaneous ignition of coal, the geological factors of coal self-ignition are identified, namely: coal bed thickness and occurrence depth, damage due to karst, moisture content, ash content, volatile yield, sulphur content, content of microcomponents of vitrinite and inertinite groups. The characteristics of these geological factors of coal self-ignition in the Moscow Basin are discussed, and the spontaneous firing hazard is categorized as high, medium and low. The ranges are set for the parameters of the geological factors belonging to different categories of the spontaneous ignition hazard. The coal self-ignition prediction is based on the data ranging model and on the idea on classifying these data with respect to their «closeness» to reference observation groups. The parameters in the new ranking scale are given weights (factors) which grow with their influence on the increase in the degree of spontaneous firing of coal. The procedure has been implemented in terms of the main operating coal bed II in the the Beltsevskaya Mine. It is found that this bed presents essential self-ignition hazard conditioned by high thickness and low rank of coal, high sulphur content and damage due to karts, and increased content of microcomponents of vitrinite and inertinite groups. All required transformations of source data and computations are carried out automatically, using macros, in the VisualBasic language for Excel.
