ABSTRACT:
A method for improved penetration of a work material using a high velocity fluid jet from a nozzle element by providing a sealed chamber between a surface of the work material and the nozzle element is described. With hard and/or irregular materials, a deformable element is provided between the nozzle element and the work surface so that the deformable element conforms to the surface to effect the seal. A preferred nozzle element assembly including the deformable element is also described. The method is particularly adapted to mining operations such as coal, hard rock excavation, and wood impregnation.
