Abstract

A tool for cutting a material along a path with a liquid jet directed onto the material for hydromechanical or hydraulic mining or for cutting mineral or bituminous material is disclosed. The tool includes a housing having an interior chamber with an opening adjacent the chamber. A nozzle body is mounted to the housing through the opening for swiveling motion about a swivel axis. The nozzle body has a first portion including a cylindrical stem symmetrically disposed about the swivel axis within the chamber and a second portion extending through the opening including a nozzle having a nozzle bore for discharging the liquid jet. A drive, operatively connected to the first portion, is provided for swiveling the nozzle body about the swivel axis.
