INTEGRATED RISK ASSESSMENT IN COAL MINING

Purpose. To determine methodological approaches to the integrated assessment of accidents and hazards of coal mining processes, which allow taking into account the mining and geological conditions of coal mining at a particular mining enterprise. Methods. Analytical methods, methods of probability theory, statistical processing of accidents at coal mines of Ukraine and methods of economic and mathematical modelling are used in the work. Results. Methodological bases for integrated assessment of hazards and harmfulness of production taking into account mining and geological conditions of coal mining are developed. It is shown that ambiguity of existing solutions both in terms of theoretical and methodological approaches, and in their practical use in coal mining enterprises, can lead to inefficient use of funds in the implementation of measures to improve working conditions. It is shown that the occurrence of accidents and hazards caused by hazardous production factors is probabilistic, so the economic assessment of these phenomena should be unified and take into account the expected economic losses in accidents and hazards and the probabilistic nature of these phenomena. Scientific novelty. For the first time it was proposed to use the economic assessment of hazardous and harmful production factors typical of the process or production as an integral assessment of accident rate, measure of hazardousness and harmfulness of a technological process or production. Practical value. The ambiguity of existing solutions both in terms of theoretical and methodological approaches, and in their practical use in coal mining enterprises, can lead to inefficient use of funds in the implementation of measures to improve working conditions. Availability of an integrated assessment of hazardous and harmful phenomena of coal mining allows taking more reasonable decisions aimed at preserving and developing the potential of the coal industry, as well as selection and justification of decisions on design and construction of new energy facilities taking into account social and economic aspects
