<p>An auger mining apparatus (10) includes a support frame (12) holding a tilt platform (18). A tilt mechanism displaces the tilt platform (18) at a pitch between 0 - 45 ° relative to the support frame (12). A stacked, dual carriage arrangement (24, 32) is carried by the tilt platform. A bidirectional auger drive system (46) is mounted to the upper carriage (32). The dual carriages are mounted for reciprocal movement along independent paths extending substantially perpendicular to one another. An auger clamp (54) mounted to the tilt platform includes a pilot member for guiding auger sections and a mechanism allowing movement on the pilot member through two separate planes; the second perpendicular to the first. The auger clamp also includes a clamp/decoupling plate and a mechanism for moving the plate in a third plane orthogonal to the first and second planes. Thus, the pilot member with the clamping/decoupling plate may also be utilized to clamp and hold an auger line in position even in steeply pitched seams.</p> |
