Abstract: A wireless initiation device comprises a power source, a processing module, a first housing and an initiation unit. The processing module processes wireless electromagnetic communications signals received by an electromagnetic receiver system associated with the processing module. The wireless electromagnetic communications signals includes a wireless electromagnetic communications signal representative of a FIRE command. The processing module is configured to generate an initiation signal upon receipt of the FIRE command. At least one of the power source and the processing module is disposed in the first housing, and the first housing has a first connector. The initiation unit has a second housing within which is disposed an initiation module that is configured to discharge initiation energy sufficient to initiate an explosive charge associated with the device. The initiation module is connected to, or connectable with, the processing module such that initiation module can receive an initiation signal from the processing module. The initiation unit also has a second connector that is configured to mate with the first connector, thereby connecting the first and second housings. The initiation module is configured to execute a sequence upon receipt of the initiation signal, the sequence resulting in discharge of initiation energy from the initiation unit.

Abstract: Systems and methods for determining vector-ratio safety factors for wellbore tubular design are provided. Pressure and temperature data for at least one load point along a tubular component of a wellbore are obtained. An effective failure axial load expected at the load point is calculated during a downhole operation to be performed along one or more sections of the wellbore within a subsurface formation, based on the obtained data. An upper boundary and a lower boundary for the effective failure axial load are determined, based on physical properties of the tubular component at the load point. A midpoint of the effective failure axial load is calculated based on the upper and lower boundaries. A critical failure differential pressure is calculated, based on the midpoint of the effective failure axial load. A vector-ratio safety factor is calculated, based on the critical failure differential pressure relative to the effective failure axial load.

Abstract: 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.

Abstract: A method of driving mine vehicles in a mine, and a transport system. A plurality of mine vehicles is arranged in succession and driven in convoy between working areas. A master vehicle in the convoy is driven manually, and slave vehicles follow the master, provided with no mechanical connection. In the working areas, the convoy is disassembled, since single vehicles are each driven separately. When assigned tasks in the working areas have been completed, the vehicles are reassembled into a convoy so as to be driven to a next working area.

Abstract: A method of reducing a highwall or sharp cliff like exposure at a mining site to gradable rubble for the purpose of reclamation is disclosed. The method includes the steps of placing a series of non-directional explosive charges at specific preselected locations on the floor of cavities created by mining, such cavities being auger holes, longwall mine areas or the like. The charges are then detonated within the cavities to create rubble. Preferably, each cavity is sealed proximate its opening on the highwall with stemming to maintain pressure within the associated cavity during the blast and to alternate the expulsion of air blast emissions. The charges are detonated to attenuate the horizontal force vectors, and to enhance the vertical force vectors such that the major effect of the blasts is exerted on the overburden to assure breakage. An improved charge for carrying out the method of the present invention is also disclosed.

Abstract: Industrial liquid wastes containing low concentrations of heavy metals are applied to a soil bed where evaporation of the liquid occurs. The soil bed is lined with a liquid-impermeable liner of polymeric sheet material, bentonite clay or a laminate of the two to prevent escape of the liquid waste to the surrounding environment. After repeated applications of wastes to the bed, the concentration of metals in the bed reaches a level where the metals may be recovered by standard mining operations.

Abstract: An ore seam or vein is mined by robbing ore from the side of a pilot hole using a gravity force broach to form a trench. The operators and most of the equipment, except for the broach, are located outside the trench. In weak formations the trench is filled with drilling fluid which lends mechanical support to its walls, and the drilling fluid may also be utilized in collecting the ore or mineral from the trench. Apparatus is disclosed for adjusting a parasite weight load on the broach to a desired value, and for providing a progressively advancing reciprocating drive for the broach.
