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 1):
A method for drilling through earthen material comprising:\n directing a gas through a pilot tube disposed below ground; directing the gas near a portion of a drilling head disposed below ground in operative communication with the pilot tube; directing the gas through an interior bore defined by a first casing segment; wherein the gas moving through the chamber carries spoils cut by the cutting head rearwardly through a second casing segment connected to the first casing segment.
