【 摘 要 】

The modernization of mining lowered the number of air-dust-methane mixture explosions, but specific value of fatal traumatism has increased threefold. Most of the miners' die from toxic gases poisoning in accidents, which means insufficient efficiency of personal protective equipment use. The cause of miners' death was inability to behave in 52% of cases. Excessive stress in miners' professional activity contributes the decline of self-control, forming disadaptive forms of behavior with characteristics of deviancy. Modelling escape to the surface using mine self-rescuers with chemically complexed oxygen among 84 individuals have had experienced protective equipment for respiratory tract has demonstrated that only 20% have covered the distance to the surface in estimated time. Strategy for solving the problems prevailed among this category of miners. The study was shut down for 80% of miners, and they had the strategy of avoiding the problems and support. Forming during respiration hyperoxygenated mixture with the help of mine self-rescuer helps forming circumstances for inadequate danger estimate and insecure behavior in extreme situation. Thus, miners' preparation for action at risk should be realized according to the strategies of behavior while respiration modelling using mine self-rescuer, providing breathing hyperoxygenated gas mixture.
