    Long-team open-pit production scheduling through dynamic phase-bench sequencing

    By Qing Wang

    In this method the state of an open-pit mine is represented by the number of benches that are mined in each predesigned mining phase (or pushback). Consequently, a specific mining schedule can be repr

    Effects of drum vibration on performance of coal shearers

    By B. Tiryaki, O. Z. Hekimoglu

    Shearer drums are a critical component in the overall performance of coal shearers, with the cutting performance depending very much on the disposition of cutter tools on the drums (the tool-lacing ar
