Patent number: 9062428Abstract: A method and pumping/drainage channel member for injecting surface water into the soil beneath a ground area includes drilling a series of holes and inserting an elongated pumping/drainage members into each hole extending downwardly into the soil. The pumping/drainage channel members comprise a cluster of integrally joined channel features each formed with a lengthwise extending slot opening. Surface water flows to the pumping/drainage member, enters the channels and drains down the pumping/drainage members to enhance water movement down into the soil to reduce runoff and help to recharge acquifers. Longer members may be installed between shorter members in a pattern to achieve more rapid injection of water deep into the subsoil.Type: GrantFiled: September 25, 2013Date of Patent: June 23, 2015Inventor: Andrew Niemczyk

Patent number: 6892834Abstract: A hard rock drill barrel has a barrel portion with a downhole hammer drill disposed therein at the barrel's periphery. A pilot portion, in substantial axial alignment with the barrel but having a smaller diameter, extends distally from the barrel for inserting into a pilot shaft of slightly larger diameter than the pilot portion. In operation, the hammer drill excavates a collar around the pilot shaft when the drill barrel is rotated and supplied with pressurized air, thereby excavating a relative large diameter shaft. The drill barrel is hollow and open at its proximal end to receive and collect cuttings flushed into the shaft above the drill barrel. The piloted drill barrel is adjustable to excavate variable diameter shaft portions, enabling the placement of casing within a larger diameter shaft portion. After adjustment of the drill barrel, smaller-diameter shaft excavation proceeds beyond the casing.Type: GrantFiled: June 18, 1999Date of Patent: May 17, 2005Inventor: August H. Beck, III

Patent number: 4134462Abstract: Apparatus and method for recovering resources from subterranean rock formations, particularly heat energy, and more particularly geothermal energy. A heat-drill, which has means associated therewith for removing some rock from the earth and forming other rock into shafts, drills into the earth and forms two shafts at the same time. Both shafts communicate with each other and with the surface and are used to circulate a drilling mud which passes through the drill body and carries off the rock being removed. The heating means is shaped in a coil or grid pattern and operates at a temperature well above the melting point of the rock, heating the rock it displaces to well above its melting point, while raising the average temperature of the total rock melted to slightly above its melting point. The drilling mud absorbs heat as it circulates and the absorbed heat is put to any desirable use, particularly by being recovered from the drilling mud by a heat-exchanger on the surface.Type: GrantFiled: September 16, 1976Date of Patent: January 16, 1979Inventor: Rufus G.
