Onasenko A. Substantiation of parameters of miners' individual means for gas and heat protection

The thesis is devoted to raising the effectiveness and safety of labour of the miners and members of the auxiliary mine-rescue detachments under extremal microclimatic conditions of the mines. On the basis of thermal-and-physical laws of influence of the environment upon the man the new complex index - Thermoindex - for control of the mine mi-croclimate in points has been developed. Its boundary values for the safe labour of the mine workers (members of the auxiliary mine-rescue detachments of the mine) under extreme microclimatic conditions have been determined. The mathematical models of heat and mass transfer in the systems "environment - gas-and-heat protective suit (cooling waistcoat) - man") have been developed. The use of their results and that one of the data of experiments allowed to create the ГТЗК gas-and-heat protective suit, the ПТК heat protective suit of the members of the auxiliary mine-rescue detachments (mine rescuers), the ОЖГ cooling waistcoat of the miners that has a minimum mass and duration necessary.
