SUBSTANCE: combine includes bioenergetic complex which brings the bit into rotation. The above bit is located in lower part of cylindrical combine along the perimetre of which the reactors filled with water and with oil above water are located. When water freezes in reactors contacting with permanently frozen soil of the well, ice displaces the oil which, when entering hydraulic pressure members, brings the seals into action by pressing them against the well walls. Seals being the counter-weight of the bit lift the bit through pulley block system a little; at that, the well space under the bit is filled with hot steam formed in reactors as a result of activated heaters arranged in reactors, which leads to softening of kimberlite. At that, excess pressure in oil reservoirs is used in electric generators for electric energy generation, and cleaned and demineralised water from reactors is directed to bioenergetic complex for regeneration of solution feeding the plants. Combine is equipped with system of wet separators and diamond reservoir, which are serviced with microescalators, manipulators and video cameras, which allows, as the combine moves downwards at any horizon of the well, taking the decision on expediency of development of kimberlite massif.

EFFECT: lower power consumption at production of diamonds, higher ecologic safety for environment.
