Cutter Head And Method For Mining Hard Rock

US Patent:

5662387, Sep 2, 1997

Filed:

Nov 8, 1995

Appl. No.:

8/555061

Inventors:

James A. Bartkowiak - York PA

International Classification:

E21C 2510, E21C 2712

US Classification:

299 55

Abstract:

A cutter head for use in the removal of hard rock. The cutter head combines a standard cutting member, such as button bits or wedge-lock cutters, with cutting blades having a diamond cutting surface. The cutting blades cutting surface is positioned above the standard cutting members so that in operation, the cutting blades form grooves in the rock face and the standard cutting members fracture the rock adjacent the grooves through tensile forces.
