摘要： 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. By automating the operation of the bootend, the need for human positioning control is reduced and the safety of operators is improved.

摘要： A belt line installation device is an apparatus designed to allow for the installation of two cranes to be mounted on a common piece of framework for use in mining. The first crane connects to the device and is installed upside down and on the left side of a conveyer where it can be used to install bottom mounted hardware on the conveyor. The second crane is installed on the top center of the invention to install top mounted hardware. This second crane also assists in loading the first crane and associated bottom mounted hardware from the pallet of hardware. The device is mounted on any quick attach equipment, such as a tele-handler or skid steer. Each crane can be powered by a PTO takeoff from nearby equipment or can be powered by a 12-volt hydraulic power pack. Each crane will be provided with wireless or pendant remote controls and a dead man switch.

摘要： The present invention relates to a mining system. The system includes a continuous miner for forming plunge tunnels from a roadway. A flexible conveyor system is coupled to the continuous miner for conveying mined material from the plunge tunnels. A controller is provided for controlling the continuous miner and the flexible conveyor system to travel along a predetermined path. Advantageously, the controller may control the drive and steering (including turning maneuvers) of the continuous miner and each conveyor module of the flexible conveyor system along the predetermined path to avoid striking either any adjacent equipment (e.g., another conveyor), or the “ribs” of a plunge tunnel being mined.

摘要： A method for estimating a level of stress that a mine truck is subjected to. The mine truck includes a frame; a container for carrying payload supported by the frame; and at least one sensor, the at least one sensor delivering signals being dependent on a force acting on the mine truck. The method includes for at least a first position of the frame, estimating a level of stress that said at least a first position is subjected to in response to a force acting on the mine truck, wherein said at least a first position is a position being different from the position of said at least one sensor; and estimating said level of stress utilising a model representation of the level of stress for said at least a first position wherein said model representation output said estimated level of stress utilising sensor signals from said at least one sensor as input signals.
