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.
