Abstract: Automated control of a longwall stageloader bootend using a plurality of sensors. The sensors include lift sensors, side shift sensors, advance sensors, angle sensors, and conveyor belt sensors. Signals from the plurality of sensors are received by a controller and used to control the operation of the bootend. Controlling the operation of the bootend includes controlling, for example, one or more lift actuators, one or more side shift actuators, one or more advance actuators, and one or more belt actuators. These various actuators can be controlled to, for example, advance the bootend, level the bootend, or match the interfaces between the bootend and a stageloader or a conveyor structure.

The conveyor chain also includes a second flight including a second side portion having a second aperture, a second flight bar, and a second sprocket-engaging portion. The conveyor chain further includes a connecting pin having a first end portion received within the first aperture and a second end portion received within the second aperture. The connecting pin couples the first and second flights together. The first sprocket-engaging portion is positioned laterally outwardly of the first end portion of the connecting pin and the second sprocket-engaging portion is positioned laterally outwardly of the second end portion of the connecting pin.

Abstract: Disclosed are vehicles used in transporting coarse ore in a mine and systems using the same. The vehicles include a drive mechanism for moving the vehicle along a surface; an inclinable conveyor positioned atop the drive mechanism for moving the coarse ore from a loading position to a discharge position; and vertically extending walls positioned along the longitudinal sides of the conveyor. The loading position of the conveyor being offset from the vertically extending walls and the discharge position of the conveyor extends beyond the vertically extending walls so that one vehicle can be positioned with respect to another to form a continuous walled conveyor. The vehicles and systems described herein do not require rails, so they can be manoeuvered within a mine to form a network from the mine face to a coarse ore unloading area.

Abstract: A conveyor chain includes a first link, a second link, and a coupler link. The first link includes a first sprocket-engaging portion and a second sprocket-engaging portion, each protruding laterally away from one another. The second link includes a first sprocket-engaging portion and a second sprocket-engaging portion, each protruding laterally away from one another. The coupler link couples the first link to the second link, and the coupler link is positioned laterally between the first sprocket-engaging portion and the second sprocket-engaging portion of each link. The coupler link includes a first joint pivotably coupled to the first link and a second joint pivotably coupled to the second link. The first joint permits pivoting movement of the first link about a plurality of axes, and the second joint permits pivoting movement of the second link about a plurality of axes.

Abstract: A link for a conveyor chain includes a first portion and a second portion laterally spaced apart from the first portion. The first portion includes a first sprocket-engaging pin, and the second portion includes a second sprocket-engaging pin. The first sprocket-engaging pin and the second sprocket-engaging pin protrude laterally away from one another. The first sprocket-engaging pin and the second sprocket-engaging pin may each have an oblong cross-section. At least one retainer can secure a connecting pin against movement relative to at least one of the first portion and the second portion, and each retainer can be positioned substantially within one of the first portion and the second portion.

Abstract: A system and method for high wall bench mining, for example, of horizontal coal seams in mountains, includes a launch platform having two side-by-side tracks for guiding mining equipment, and utilizes two continuous miner machines and conveyor cars. Two side-by-side mine entries can be worked simultaneously, one miner advancing deeper into the coal seam and conveyor cars being added behind the miner at a first mine entry, and the mining completed and cars and miner retreating and being extracted from a second mine entry. As conveyor cars are being extracted onto one track from the mine entry that a string is retreating from, the cars are moved across the launch platform to the other track and are added behind the advancing miner machine launched from that track into the other mine entry.

Abstract: A mining machine including a frame, a cutting head moveably coupled to the frame and pivotable about an axis that is substantially perpendicular to a first mine surface, and a first actuator for stabilizing the frame relative to the first mine surface. The first actuator is coupled to the frame and includes a first end extendable in a first direction to engage the first mine surface. The extension of the first actuator is automatically controlled based on measurements of at least one indicator of the force between the first actuator and the first mine surface.

Abstract: A method is provided for removing slack in a chain conveyor driven between a first sprocket and a second sprocket, the first sprocket and the second sprocket rotating in a first direction. The method includes: locking the second sprocket to prevent rotation of the second sprocket in a second direction opposite the first direction; operating the first sprocket in the second direction to position a slack portion between the first sprocket and the second sprocket; and removing at least one chain link from the slack portion.

Abstract: Systems and methods are provided for detecting face alignment and face steering of a longwall mining system. The system includes a detection device mounted in a maingate roadway and a first indicator device mounted on a shearer of the longwall mining system to indicate a position of the shearer to the detection device. The system further includes a controller coupled to the detection device. The controller determines a shearer path of the shearer as the shearer moves along an ore face. The shearer path is determined based on a signal from the first indicator device received by the detection device. The controller generates an indication of face alignment based on the shearer path.
