ABSTRACT:
A manifold for a borehole miner, wherein the manifold is rigidly secured to a first and a second pipe of a pipe bundle; movably connected to at least one other pipe; and provided with a collimating nozzle unit associated with a deflector plate unit, such that a pressurized abrasive jet spray can be directed against the walls of a bore hole, and the back splash from the jet spray will be prevented from adversely affecting the pipes in the pipe bundle by the deflector plate unit.
