Abstract:
An earth boring apparatus may include an earth-boring cutter head, and a casing secured to the cutter head and extending rearwardly therefrom so that the casing and cutter head are rotatable together as a unit. A casing cuttings passage may extend from adjacent the casing front end to adjacent the casing back end. An entrance opening of the casing cuttings passage, which is adjacent the cutter head, is adapted to allow cuttings to move through the entrance opening into the casing cuttings passage. In some implementations there may be a stationary auger positioned within the casing cuttings passage rearwardly from the entrance opening, such that the stationary auger does not rotate when the casing and cutter head are rotated together as a unit.

Claim (Index 8):
The method for drilling through earthen material of  claim 1 , further comprising:\n directing the gas through the interior bore of the first casing segment while the first casing segment is rotating about a longitudinal axis; directing the gas to flow through a tapered portion of the first casing segment.
