  • Patent number: 12723512
    Abstract: The present invention relates to a mining system including a continuous miner. The continuous miner mines material and includes a miner navigation system. The mining system further includes a flexible conveyor system for receiving the mined material from the continuous miner. The flexible conveyor system includes a conveyor navigation system. The mining system further includes control means for controlling the miner navigation system and the conveyor navigation system so that the flexible conveyor system receives the mined material from the continuous miner. Preferably, the flexible conveyor system need not be coupled to the continuous miner, and can be extracted separately in the event of a cave-in on the miner.

  • Patent number: 12146409
    Abstract: 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.

  • Patent number: 11597605
    Abstract: The present invention relates to a flexible conveyor system. The system includes a supply conveyor module and a receiver conveyor module. A hitch mechanism is provided for pivotally coupling the supply conveyor module to the receiver conveyor module about a pivot axis so that the receiver conveyor module receives conveyed material from the supply conveyor module proximal to the pivot axis. Advantageously, the receiver conveyor module receives conveyed material from the supply conveyor module proximal to the pivot axis which impedes spillage between the adjacent conveyor modules on very tight corners.

  • Patent number: 10113425
    Abstract: The present invention relates to a mining method including the step of forming one or more sets of gate roads. Each set of gate roads includes at least two headings typically for providing and retuning ventilation. Dead end plunge cuts extend from the sets of gate roads. Each plunge cut is formed with a continuous miner coupled to a flexible conveyor system. Each plunge cut is greater than 30 meters in length. Advantageously, narrow elongate pillars may be left between adjacent plunge cuts, thereby resulting in greater material removal per volume and improved operating costs when compared with bord and pillar mining.
