“…Thus, for example, we believe that in order to ensure labour safety of coal mine personnel in conditions of FD accumulations in working areas of mine workings it is necessary to develop a normative method of early identification of places of formation of increased concentrations of FHEM for their subsequent continuous monitoring. In addition, it is necessary to develop additional organisational and methodological measures, both for occupational health and safety, for timely notification of workers about specific locations of hazard sources, methods of forecasting their formation and development, as well as prevention of FHEM fire/explosion and reduction of consequences of the impact of hazardous factors of explosion of local FD accumulation [13,[17][18].…”

This article presents a methodological approach to solving the problem of predicting local methane accumulations in order to prevent occupational injuries resulting from explosions of methane-air mixtures. On the basis of the analysis of accidents that occurred in coal mines and industrial injuries of miners (mine workers) it is established that the leading role belongs to explosions of methane-air mixtures. The method/methodology considered in the article is based on a comprehensive analysis, first of all, of both mining and geological and other influencing factors and conditions of operating mines of the Pechersk coal basin, as well as aerogas-dynamic processes of mass transfer of air flows in mine workings. The assumption about influence of mining equipment on the process of formation of methane accumulation sites is made. The algorithm of consecutive actions of managerial engineering and technical personnel to reduce industrial injuries is proposed. The developed algorithm implies the use of applied software for modelling aerogas-dynamic processes in the mining excavation operating region. FlowVision and ANSYS Fluent application software packages were selected to determine the methane accumulation locations based on the analysis of existing application programmes.

The injury rate in underground coal mining is extremely high. One of the factors leading to injuries in underground mining is rock bursts. Although rock bursts are not the most common cause of injury in this industry, their consequences are extremely severe. At the same time, the level of injuries as a result of the manifestation of this factor remains high and almost does not change over the past years. The paper presents a method for determining the risk of injury of varying severity as a result of rock bursts. Multifunctional security systems that allow obtaining information about the state of the rock mass are analyzed. Based on the data obtained from these systems, the probability of a rock burst is assessed. The paper also deals with the processing of statistical information on light, severe and fatal injuries caused by rock bursts in the coal mines of the Kuznetsk coal basin. On the basis of statistical data and the results of measurements of the main parameters of the rock mass, the value of the individual risk is determined. It is advisable to correlate the obtained value with the average occupational risk in production.

Purpose. Determination of the noise induced permanent threshold shift for a coal miners in five main working professions, taking into account the noise impact on the way to the workplace and back based on data obtained from personal sound level meters. Methodology. A strategy is selected for measuring the level of noise exposure at workplaces No. 3 per workday (GOST ISO 9612-2016) in a coal mine. Personal sound level meters were attached to the miners shoulders; they measured the noise level on the way to the workplace, during the work shift (8 hours) and on the way back. The processing of the measurement results was carried out on the basis of a quantitative assessment of the noise impact on workers according to the noise induced permanent threshold shift (NIPTS). The NIPTS values were calculated for a period from 3 to 30 years for 5 main professions, taking into account the noise impact when moving to the workplace and back. Findings. The values of the equivalent noise level at miners workplaces of are determined, which are 15 to 20 dBA above the maximum permissible equivalent level (80 dBA). Based on the results obtained, a constant shift in the hearing threshold was forecast for workers of five occupations with seniority of 3 to 30 years. A reduction in the hearing threshold of a sinker will amount to 25 dB in 30 years, which corresponds to the occupational disease Stage 3. Originality. Constant displacement of the hearing threshold for workers in coal mines, caused by the effect of an increased noise level during the journey to the place of work and back, was revealed. Practical value. It was found that in order to prevent the development of an occupational disease (sensorineural hearing loss) in underground miners, it is necessary to measure the noise level by using personal sound level meters for an 8-hour working day, taking into account the way time to the workplace and back. Noise exposure assessment should be based on a continuous decrease in the hearing threshold.
