Abstract

As the demand for mineral resources increases, the need to underground mining is promoted and due to technological advances, deeper deposits with lower grade mineralization are becoming valuable. In underground operations, it is common practice that each area is planned individually. As these techniques often ignore how designing and planning one section can affect other sections, , optimum individual planning fails to provide an overall optimum design. In recent years, there has been a growing interest in simultaneous optimization that may assist with integrating different areas of the mine planning process and providing more profitable mines plans. In this paper, a mathematical IP model has been developed that simultaneously optimizes stope layout designs and production schedules for sublevel stoping (SLS) iron ore operations, and it is demonstrated that an integrated scheduling method can produce the globally optimal scheduling result by taking into account all interactions that occur across the stope layout optimization and scheduling. In this case, the application of the optimal integrated scheduling approach increases final NPV by 16 percent in comparison with the isolated approach.
