Summary
High investment and operating cost require miners to make maximum utilization of equipment they select. To fully utilize equipment, individual units of the equipment set should be selected to attain the most profitable match ratio and interaction effficiency. A mining cost generator and machine matching program were developed to calculate production and owning and operating costs for individual machines and then determine cost per unit of output for each combination. The combination with the lowest cost per unit of output is optimal. The cost calculation reflects cost penalties for both under- and excess-capacity based on overtime operation and machine interaction efficiency. Hourly production, investment, and owning and operating cost per hour for each type of machine are the most important variables in determining cost per unit of output. The match ratio and interaction efficiency appear to become more important as the number of machines working in combination increases. The relative cost of under- and excess-capacity are determined by analyzing the impact on total cost and total production of a one machine increase or decrease of each type of unit in the combination, not by examining what that machine is theoretically capable of accomplishing by itself.
