ABSTRACT
The paper analysis the new technological principle of sinking of vertical workings by means of the thermal melting of rocks. The theoretic geomechanic tasks of the radial fracturing of the rockmass for a possibility of the transport of the molten rock into the arisen cracks are analyzed. Also the theoretical tasks of the controlling of the process from the point of view of the securing of the continual optimal advance of the flame injector as the transferrer of the thermal energy into the rockmass are analyzed.
