    摘要: An injection system and method is described. In several exemplary embodiments, the injection system and method may be a part of, and/or used with, a system and method for excavating a subterranean formation. In at least one example, an apparatus is provided that includes a source of impactors comprising at least some ferritic material capable of influence by magnetic fields. An injector is coupled to the source and includes a screw extruder, a screw positioned within a barrel, and at least one magnetic circuit is positioned outside of the barrel.

    摘要: A system and method for excavating a subterranean formation according to which a fluid is introduced into a vessel to draw a plurality of impactors into the vessel to form a suspension. The suspension is discharged from the vessel and into another vessel, and fluid is introduced into the other vessel to draw the suspension into the other vessel. A suspension is formed in the other vessel that is discharged towards the formation to remove a portion of the formation.

    摘要: A system and method for excavating a subterranean formation, according to which a slurry of liquid and a plurality of impactors are introduced into at least one cavity formed in a body member and are discharged from the cavity so that the impactors remove a portion of the formation. The impactors are separated from at least a portion of the fluid and the materials removed from the formation, so that the impactors can be reused.
