PCT No. PCT/EP88/00593 Sec. 371 Date Sep. 29, 1989 Sec. 102(e) Date Sep. 29, 1989 PCT Filed Jul. 5, 1988 PCT Pub. No. WO89/01396 PCT Pub. Date Feb. 23, 1989.To cut, bore or similarly machine rock, ore, stratified coal or other objects, a medium is delivered under high pressure through a supply pipe to a nozzle. The supply pipe is designed as a pendulum-type pipe, in particular in the form of a flexible high-pressure hose, and executes, together with the nozzle, rapid, for example oscillating and/or circular, movements along a guide. In this way, straight cuts and/or holes can be made very rapidly and simple in rock. The cut width can be controlled by the arrangement and fitting in particular of a plurality of nozzles, depending on the rock and pressure medium. In particular, an eccentric element which functions as a drive mechanism permits a circular movement of the nozzle. |
