299017000 | Jetting (e.g., hydraulic mining) | 7 |
20100090516 | METHOD FOR SUB-GLACIAL MINERAL RECONNAISSANCE AND RECOVERY - A method for sub-glacial mineral reconnaissance and recovery comprises analyzing silt and solutes in fluvial sub-glacial streams of a glacier. Boreholes are formed in the glacier and melt-water flow is analyzed to establish concentration gradients of minerals in the solutes and sediments. After significant mineral deposits are identified, conventional mining techniques may be used to recover minerals. | 04-15-2010 |
20110204699 | DEVICE AND A METHOD FOR MOVING A JET MEMBER - A device for moving a jet member in a first path over a layer to be treated by the jet has means configured to enable input of data relating to a geometrical shape of a surface of said layer to be treated by the jet member and means configured to use said data for calculating end positions (S | 08-25-2011 |
20110309668 | METHOD FOR CONVERTING HYDRATES BURIED IN THE WATERBOTTOM INTO A MARKETABLE HYDROCARBON COMPOSITION - A method for producing hydrocarbons wherein hydrates are excavated from the sea bottom and mixed into a transportable slurry, the slurry being pumped to a support vessel, using near sea bottom positive displacement hydraulic pumps, where the hydrates are converted into a hydrocarbon containing stream, with excavation tailings being pumped down to hydraulic motors to drive the hydraulic pumps. | 12-22-2011 |
20130106166 | Horizontal Borehole Mining System and Method | 05-02-2013 |
20130127231 | Hydraulic Mining System for Tabular Orebodies Utilising Directional Drilling - A mining system for extracting ore using directional chilling techniques to obtain access to the orebody. Spaced-apart roadways are formed in the ore formation, with a downhill roadway being lower in elevation than the other roadway, and the downhill roadway having a ditch therein draining downhill. A borehole is formed between roadways in the ore formation using the directional drill bit, and then the end of the drill string is equipped with a jetting nozzle. The jetting nozzle is moved within the borehole to erode the formation and mine the ore. In one embodiment, a slurry of mined ore and jetting fluid flows as a slurry down the intersection of the mined face and the floor towards a ditch formed in the downhill roadway. In another embodiment, a slurry of the mined ore and the jetting fluid flows down the borehole, and then down the ditch formed in the downhill roadway. In each case, the ore flows down the downhill roadway to a sump. From the sump, the ore is carried to the surface for transportation and eventual refining or use. | 05-23-2013 |
20140097664 | DEVICE FOR NON-ENTRY MINING - A bore hole tool | 04-10-2014 |
20150368920 | FRAME MOUNTED HYDRODEMOLITION SYSTEM FOR TREATING LARGE INCLINED WALL SURFACES - A steeply inclined surface is hydrodemolished by providing a staging platform and a rig that includes a base frame defining a planar footprint within the frame. The rig is suspended from the platform by a cable such that frame is coplanar with the surface and the incline of the surface causes the rig to lean against it. Rails are provided on the surface to restrain spurious lateral movement of the rig. The rig is positioned on the surface and nozzles mounted on a trolley within a travelling carriage on the frame travel in two dimensions to hydrodemolish the surface within the footprint. The rig is moved vertically along the rails and laterally along the platform to reposition the rig to work a new section of the surface in conjunction with other rails that are also mounted on the surface. | 12-24-2015 |
