Abstract
A system and method for excavating a subterranean formation, according to which a suspension of liquid and a plurality of impactors are passed between a drill string to a body member for discharge from the body member to remove at least a portion of the formation. The flow of the suspension between the drill string and the body member is controlled by an ultra shearing drilling mud in order to prevent the impactors from settling near the bottom of the formation.
