1. Your mine is planning a brownfield expansion by developing a satellite pit some 10km away from the ROM pad. The equipment requirements to mine this pit must be determined. One of the factors used to determine equipment requirements is machine productivity (or the tempo/ rate of work) of a machine. How will you go about to determine the productivity factors to be used in the requirements exercise for each of the primary equipment (drills, shovels, and trucks) to be used. Discuss each machine type separately [18] 2. Explain five LOM schedules that are typically generated as part of a LOM planning exercise [15] 3. Discuss two types of shift cycles. Elaborate on their advantages and disadvantages. [7] 4. Name five goals of short-term production scheduling and explain how it differs from long-term scheduling (i.e. LOM planning). [15] 5. With reference to the lecture notes, explain in detail to a class of mining engineering undergraduates the three concepts available to a mine planning engineer when he/she wants to "optimise" the LOM production schedule of a mine. [15] 6. Describe the typical components of an ore stockpiling strategy. Note the question is not to describe the uses of stockpiles. [10] 7. What constitutes a cost-effective mining production schedule?
