ROCK SAMPLING APPARATUS

摘要

The present invention uses an Oscillating Disc Cutter (ODC) in a controll ed manner to cut rock for assay purposes. The ODC (1) is mounted in an elong ate guide frame typically in the form of an open box channel (2). The ODC is located on a carriage (3), the carriage itself mounted on guide rails (4) w ithin the channel (2). The apparatus includes drive means operable to drive the carriage (3) in a rectilinear manner along the rails (4) such that the r ails (4) define a cutting path. The ODC cuts a groove of controlled width an d depth in a rock face, yielding rock chips that can be used for accurate as say of the face.
