Abstract The using of the plasma technology in Mining was limited because of the its specificity (the large capacities, the limited environment, the poor condition of work etc.) and was less used on practice. The main aim of the work is the development of a new direction in the plasma technology - the plasma technologies of Mining Industry. For implementation of this goal the following activities were done: The perspective areas of using the plasma technology in Mining have been detected. This is the using plasma-flow to break the solid rocks; to process a surface of the building materials made from the solid rocks; to drill rocks; to recycle the mining industry wastes; to produce and repair the equipment of Mining Industry. The replacement scheme of the plasma-arc operation was done which is based on the analysis of the electrophysical processes occurring in plasma equipment and analysis of electromagnetic processes was conducted by using the classical mathematic methods. Its an algorithm of solutions and a program were created on base of which the original methods of the plasma-flow formation and the designs of plasma device were developed for using in Mining. On base of the analysis of electromagnetic processes those criteria of power-supply of plasma-device were established that provide an effective operation of plasma-torch. The effective operation of the plasma torch is possible when the current-voltage characteristic of power-source is a slant line and its tilt angle close to 90 0 . The power-supply is not a "voltage-supply" it's a "current-supply" ie., when the plasma-arc resistance is changing the voltage is changing not the current and the maximum voltage of idling should be only 10-15% more than maximum working-voltage. The current-voltage characteristic of power-source should have a rectangle shape, ie, the power-source should be a "current source" in the working and short circuit regime and a "voltage source" in an idling regime. On the basis of the experimental data and theoretical calculations the comparative analysis of the cooling process of an anode by different methods has been done. The convective cooling (by water and by air) was compared with the cooling-process caused by the boiling of water. It is established that the cooling of the electrodes by the boiling of water is equal to the convective cooling by water. Also, the analysis of the thermal processes of plasma-flow action on the surface of the solid rock was done. The mathematical description of the temperature distribution in rock is based on the equation of thermal conductivity for the 1D space. The solution of this equation for the boundary conditions, which stipulates the changing of the temperature of the rock surface at any instant and the maximum temperature deviation, shows that the temperature distribution in rock is subordinated to wave model. That leads us to the conclusion that when a sufficiently large temperature gradient is generated, any rock will be broken. On the basis of this work, carried out in the theoretical part, the advanced methods of the plasma-flow formation and the design solutions are created, some of which are patented and introduced in production. vii
