INTEGRATED DEVICE FOR DRILLING, DECOMPACTION AND CHISELING OF ROCK BASED ON HIGH-PRESSURE FOAM Russian patent published in 2019 - IPC E21C37/06 

FIELD: technological processes.

SUBSTANCE: group of inventions relates to drilling and decomposition of rock based on high-pressure foam. Device includes mechanical device for drilling, decompaction and chiselling of rock, system of high pressure foam generation and supply and device for holes closing. Integrated device for drilling, decompaction and chiseling of rock includes power supply, impact piston, engine, driving gear unit, rotary drilling bit, drill pipe, apparatus for sealing of drilled holes, high-pressure foam supply chamber, system of high-pressure foam generation and supply consisting of hydraulic pump, gas pump, mixer for gas-liquid mixture and injector. System can control proportion of gas-liquid mixture ingredients and feed pressure for operation with rock of different hardness and based on various operating conditions.

EFFECT: higher efficiency of drilling, prevents defects of holes closing, possibility of continuous drilling and decompaction of rock by means of integrated solution.
