  • Modelling And Optimizing An Openpit Truck

    Modelling And Optimizing An Openpit Truck

    This paper addresses a special truck scheduling problem in the open-pit mine with different transport revenue consideration. A mixed integer programming model is formulated to define the problem clearly and a few valid inequalities are deduced to strengthen the model. Some properties and two upper bounds of the problem are proposed. Based on these inequalities, properties, and upper bounds, a.

  • A Pushback Sequencing Model For Production

    A Pushback Sequencing Model For Production

    A dynamic sequencing method has been developed to simultaneously optimize the coal production rate, waste stripping rate, mining sequence, and mine life of an open-pit coal mine. The method first establishes a geological seam model of a bedded coal deposit which estimates the relevant attributes of coal seams at the center of each block on the X-Y plane.
