  • Method of electrothermomechanical drilling and device for its implementation
    Patent number: 5479994
    Abstract: The proposed invention relates to the mining industry and may be used for drilling wells in loose rock, in particular in quaternary deposits and in technogenic rocks with simultaneous durable and ecologically clean tubingless well cementing. The proposed method is based on loosening of the rock by its preliminary drying at the temperature of 400-450 K., its dehydration at the temperature of 700-750 K., burning out organic admixtures and its dissociation with separation of the gaseous phase at the temperature of 750-950 K. with subsequent compacting by means of the rock-crushing instrument mounted at the lower part of a thermomechanical penetrator, and on thermal transformation of the compacted rock (caking, roasting, fusion) by means of a cylindrical heater with the working temperature of 1800-2300 K.
