Optimisation of cutting cycles in conventional underground coal sections to improve productivity : ウィキペディア英語版 | Optimisation of cutting cycles in conventional underground coal sections to improve productivity
Optimisation of cutting cycles in conventional underground coal sections to improve productivity serves as an area of study that deals with the utilisation of the machines in conventional underground coal sections. Utilisation of machines focuses on reducing the time that machines spend idle and increasing the amount of time during shifts that machines are actively contributing to production. This can be addressed through effective planning of the cutting cycle parameters or by adjusting the design of machines to modify the cutting cycles ==Conventional coal mining== Conventional underground coal mining relies upon the use of continuous miners in order to extract coal reserves from underground coal seams.〔(【引用サイトリンク】title=The use of continuous miners in South African coal mines )〕 In combination with the continuous miners, shuttle cars are used to transport the extracted coal from the face to a transfer point (feeder breaker). From there the coal is typically tipped onto the underground conveyor system, which transports the coal to the surface in order to be distributed to customers. Effective management of the cutting, loading and tipping cycles utilised in the sections serve as a possible area for productivity improvement.
