Abstract

At hydroshafts, all hydromonitors are rigidly connected to the supply steel pipe, which does not ensure achieving the optimal distance from the nozzle to the bottom hole chest during the whole time of hydrodrilling. We consider a technical solution for making self-propelled hydraulic motors moveable during hydrodrilling. The most acceptable variants are the feeding-energy-conducting packet based on "Nurenberg shears" and the daisy-chain telescopic energy-conducting packet (TPP). Parameters of the new TPP and operational and technical performance of self-propelled hydromonitors with this device at cleaning are obtained. The increase in the productivity of hydrowinning can be 25-30 %, which should be considered as significant.
