Tynyna S. Justification of parameters of air temperature normalization of development working dead ends in deep mines using vortex air conditioners

The purpose of current investigation - to study the process parameters temperature normalization bottom zone of development workings in deep mines using eddy of air conditioners by improving the efficiency of the systems of normalization of air mine atmosphere by utilizing a hot component, obtained during the vortex flow distribution. Research object: process of normalization of temperature parameters of mine atmosphere in the system of the dead-locked preparatory making. Research subject: the methods of air temperature normalization in the bottom-hole zone of dead-end development workings in deep mines using vortex air conditioners that are utilized in the process of temperature normalization and operated with recycling of a hot component obtained as a result of vortex separation. As a solution of the set tasks a complex method could be used. This method plugs: theoretical researches of normalization of temperature and utilization are hot components, which is based on fundamental positions of aerogasdynamics and mechanics of continuous environments; laboratory investigations of circular devices working at the supercritical overfall of pressures and assuming an active management of working processes; the method of the scientifically reasonable raising of experiment with the use of regressive analysis theory and mathematical statistics; experimental researches in the conditions of operating mines, carried out in the certain coalface of the preparatory elaboration. The conformity of circulation speed of normalizing air along the surface of butt end of coalface from the geometrical and gas-dynamic parameters of making and normalizing device is firstly set. The experimentally-statistical mathematical regressive model of speed change of the gradient of temperatures is first worked out at normalization of parameters of the dead-locked making that shows intercommunication between the parameters of vortex conditioner and parameters of elaboration. Classification of air normalization methods is worked out on the method of utilization of hot gas. Methodologies of realization of laboratory and experimental researches of construction of vortex mine conditioner pilot-scale, which works with utilization of hot component, are also worked out. Designer documentation is worked out and the model of the circular ducted device is made with possibility of the active adjusting of his geometrical parameters. The construction of vortex conditioner is worked out with utilization of the hot constituent got at the division of normalizing gas. The construction of circular ejector, that assumes the active change of geometrical parameters, is made. The construction of vortex conditioner, working with utilization hotter than making, executed on a sectional chart that is tested in the conditions of A.F. Zasyadko Mine, and SE F.E. Dzerzhinsky Mine, SS "Dzerzhinskugol."
