GEAR TO DRIVE WORKINGS IN GEOLOGICAL STRUCTURES Russian patent published in 2004 - IPC

FIELD: technology of driving workings in sedimentary rocks by action with energy of jets of working agent under pressure on to crushed environment. SUBSTANCE: gear includes elongated body in which working space power plant is housed to provide working agent to drilling equipment in the form of working tool put on one face of body, opposite face of body of gear is fitted with auxiliary working tool with fixture for intake of fuel components ( oxidizer and fuel ) and cooling agent, that is, components ensuring serviceability of gear while conducting auxiliary and basic operations. On side of fixture gear is equipped with module unit in the form of energy-independent autonomous apparatus traveling in space of hole or working formed by mentioned gear. Auxiliary module and mobile apparatus includes units fitted with valves for fuel transfer from it into main power plant of gear which markedly enhances driving effectiveness and expands potential of gear while selecting conditions and parameters of all operations of working driving, clearing working space from slime, formation of walls of working thanks to execution of several forward and backward shuttle movements of gear along space of driven and drove working, application of polymerizing substance on walls of working and action on these walls with streams of working medium of different temperatures. EFFECT: enhanced driving effectiveness and expanded operational potential of gear. 2 cl, 6 dwg
