| 20100276983 | INTEGRATION OF AN IN-SITU RECOVERY OPERATION WITH A MINING OPERATION - This description is directed to a method and system for integrating an in-situ bitumen recovery operation with a bitumen mining operation for improved efficiencies and synergies therebetween. The method comprises obtaining a production fluid from the in-situ bitumen recovery operation, directing the production fluid to the bitumen mining operation, and incorporating the production fluid into the bitumen mining operation. The basic integrated system comprises a production well for recovering production fluid from the in-situ bitumen recovery operation, a bitumen mining and extraction facility, and a transporter for directing the production fluid from the production well to the bitumen mining and extraction facility for incorporation into the mining and extraction operation. The in-situ recovery operation may be a thermal operation, such as steam-assisted gravity drainage (SAGD), cyclic steam stimulation (CSS), or a derivative thereof. | 11-04-2010 |

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. | 05-05-2016 |

| 20080315665 | APPARATUS FOR ASSEMBLING A LINER - An apparatus for assembling a liner from a plurality of longitudinal sections of flexible material having longitudinal edges adapted to be joined one to another to form the liner includes a path means along which the longitudinal sections of flexible material can be conveyed in a laterally reduced condition, an assembly zone at which the longitudinal edges can be joined together to form the liner, and a guide structure about which the flexible material can turn upon exiting from the path means to provide an inner section and an outer section turned back with respect to the inner section. The guide structure presents a guide, surface over which the longitudinal sections of flexible material can pass, the surface being configured to facilitate spreading of each longitudinal section from the laterally reduced condition. | 12-25-2008 |
| 20100019562 | Non-Motorized Gold Mining Apparatus - A non-motorized apparatus for collecting particulate materials, including gold, in stream placer deposits, comprising a first tubular member, a second tubular member, a riffle tray with perforated ridges, a skirt for enveloping the tubular members and directing stream flow, and a fibrous matting held entirely inside the second tubular member. The second tubular member is connected to one end of the first tubular member in a way that a high velocity stream flowing into the first tubular member creates suction pressure in the second tubular member. The particulate matter settles in grooves formed by the ridges in the riffle tray and passes through perforations to become trapped in the fibrous matting as the stream is drawn into the second tubular member. | 01-28-2010 |
| 20130099552 | METHOD OF MINERAL FUEL BENEFICIATION WITH SUBSEQUENT DELIVERY TO THE CONSUMER BY PIPELINE TRANSPORTATION - A method of mineral fuel beneficiation with subsequent delivery to the consumer by pipeline transportation relates fuel and energy complex and can find application in coal and slate energetics. Invention main objective is security of solid fuel delivery from mine (or an open cut coal mine) in already enriched form, with its subsequent through delivery to the consumer by pipeline on any distances in stream mode, without any intermediate transshipment operations. For this purpose use liquid with set complex physical, sanitary-and-hygienic and ecological properties, simultaneously, in 4 qualities: As environment for grinding material that needed further reduction of size; As separation environment for the subsequent, after reduction of size, deep underground gravitational enrichment of combustible mineral, As motionless filler of the vertical pipeline, for buoyancy in it ready product from mine on terrestrial surface: As carrying medium for final drift of end-product to the consumer by main pipeline. Depending on consumer type of solid fuel, a time of year, and weather conditions in which such, non-polluting, mining-energetic complex functions, there are used various technological approaches as to the general principles of construction of such, non-polluting, beneficiating transport technological process as well as within the limits of separate links of such technological chain, various methods of the regeneration, used many functional liquids which are in the closed contour of circulation between producer of solid fuel and its consumer. | 04-25-2013 |

| 20080197689 | Non-motorized gold mining apparatus - A non-motorized apparatus for collecting particulate materials, including gold, in stream placer deposits, comprising a first tubular member, a second tubular member, a third tubular member with perforated ridges, a skirt for enveloping the tubular members, and a fibrous matting disposed over the third tubular member. The third tubular member with the fibrous matting is held entirely inside the second tubular member. The second tubular member is connected to one end of the first tubular member in a way to have high velocity stream flowing into the first tubular member, creating a suction pressure in the second tubular member. The particulate matter settles in grooves formed by the ridges in the third tubular member and passes through the perforations to be trapped in the fibrous matting as the stream is sucked into the second tubular member. | 08-21-2008 |
