ABSTRACT
Traditional mine production scheduling relies on generating pushbacks with price parametrization and aggregating the blocks inside these pushbacks into benches to generate long term annual production schedules. The incremental fashion of obtaining pushbacks fails to incorporate the operational requirements such as multi capacity, multi destinations, blending requirements, truck hours and stockpiles. Since many production schedule plans highly depend on the design of pushbacks, poor designs will prevent the schedules from achieving a maximum NPV or even obtaining a feasible solution. In this paper, block by block yearly schedules will be generated by solving the mine production scheduling problem under the operational requirements and the resulting yearly schedules will be grouped into phases for the pit design. Then, the schedules based on the traditionally generated phases will be compared against the schedules obtained by direct block scheduling guided phase designs.
