    摘要： An in situ method of mining is disclosed. In one non-limiting embodiment, the method includes: defining an ore volume; drilling a large number of vertical boreholes; forming lateral boreholes from at least some of the vertical boreholes; transporting the ore cut during drilling of the vertical and lateral boreholes to a surface location; and separating the ore received at the surface from other materials. Additional ore may be extracted fracturing and/or leaching the formation surrounding the drilled boreholes. The residual ore at the surface may be disposed by pumping it into already drilled boreholes or underground storage facilities.

    摘要： A reamer bit for use in earth boring operations comprising a body, cutter mounts having rolling cutters on the bit body, and stabilizers pads on the body placed between adjacent cutter mounts. The reamer may further include a pilot bit on a drill pipe extending downward from the reamer body. The reamer bit outer periphery with its stabilizers and bit body has a radial profile approximating a circle thereby reducing dynamic perturbations during drilling operations.

    摘要： Cutting elements, earth-boring drill bits having such cutting elements and related methods are described herein. In some embodiments, a cutting element for an earth-boring tool may include a superabrasive table having a recessed surface in a cutting face thereof and a shaped feature in a substrate at the interface between the superabrasive table and the substrate, the shaped feature corresponding to the recessed surface in the cutting face of the superabrasive table. In further embodiments, a cutting element for an earth-boring tool may comprise a superabrasive table positioned on a substrate, and at least one substantially planar recessed surface in a cutting face of the superabrasive table. In yet additional embodiments, a cutting element for an earth-boring tool may comprise a superabrasive table positioned on a substrate, and at least one non-planar recessed surface in a cutting face of the superabrasive table.

    摘要： Earth-boring drill bits include a bit body including a blockage-resistant internal fluid passageway. The blockage-resistant internal fluid passageway includes at least one internal fluid passageway formed in the bit body and a cuttings filtering feature formed in the at least one internal fluid passageway configured to prevent at least some cuttings from flowing through the at least one internal fluid passageway. In one embodiment, the cuttings filtering feature includes at least one lateral member extending transversely across the at least one internal fluid passageway. In another embodiment, the cuttings filtering feature includes forming a central portion of the at least one internal fluid passageway with a width along a lateral axis thereof less than an average width of a fluid path extending through a nozzle disposed at least partially within the at least one internal fluid passageway. Methods of forming the blockage-resistant internal fluid passageway are also disclosed.

    摘要： An earth-boring bit has a bit body having a plurality of bit legs extending longitudinally therefrom, each bit leg comprising one or more groove regions formed along a laterally outer surface thereof. Each groove region comprises a fluid course for drilling fluid and cuttings to pass across the outer surface. A ridge may be disposed adjacent a lower edge of one or more of the groove regions. Each groove region may also be positioned at differing heights on the bit legs. Methods of forming earth-boring bits are also disclosed.
