Abstract.

A procedure for the identification of hazards and risk assessment, which determines the procedure for identifying hazards and assessing the risks of enterprise activity in the field of labor protection has been developed. The procedure was implemented at the enterprises of the Coal Business Unit of DTEK ENERGO LLC. It was established that the risk of injury is determined both by the adopted mining technology as a whole, and by the specific features of the main and auxiliary processes and operations that are characteristic of each particular mine, which in turn are also determined by the individual characteristics of miners. Only in 4 cases (17 %) did the priority of the risk assessment not coincide with the actual cases of injuries. This indicator can serve as a criterion for the accuracy of determining the priority of risk assessment by an expert group. The priority of risk assessment for a given technological operation must be adjusted taking into account the actual incidents of injuries. An analysis of risk assessment cards indicates that 88 % of injuries occurred during normal operation and only 12 % as a result of an emergency. The probability of injury and, accordingly, the risk during normal operation is higher than in an emergency. This must be considered when assessing the consequences of risk. The distribution of the number of sources by various types of danger showed that 31 % of the sources of danger relate to the collapse of the rock mass, 15 % – to the collapse of objects, materials, 12 % – to explosions or fires, and 8 % – to flying objects and moving equipment. For such a hazard as “collapse of the rock mass”, for which the largest number of sources of danger and injuries were recorded, the risk is at the same or even lower level as for hazard types with a small number of sources (injuries). It is advisable to adjust the risk, first of all, its probability, taking into account the actual cases of injuries. It is also necessary to expand the ranges of probability estimation and consider it as a continuous value that changes, for example, from 0 to 100 %. Recommendations on improving the procedure for hazard identification and risk assessment in coal mines are given.
