ABSTRACT:
A hydro-mechanical device for underground drilling for use with a drilling rig comprises a container having a combustion chamber, an ignition system, inlets for introducing a fuel, an oxidizer, a liquid into the combustion chamber, a nozzle for discharging combustion products, a piston slidably mounted in the container and a reamer connected to the piston. The ignition system provides electro-discharges in the fuel, oxidizer, liquid mixture. Each electro-discharge has an explosive nature and produces combustion products having a high pressure. Combustion products are ejected through the circular nozzle surrounding the container to provide a thermal drilling action. The movable piston is pushed downwardly by the products of electro-discharge and causes the reamer to penetrate rocks or a frozen ground to provide a percussion drilling action. By the use of combined effect of thermo-percussion drilling, holes of significant depth can be drilled and rocks or frozen ground of high hardness can be pierced. The present invention is adapted for underground and undersea drilling.
