Abstract: Considering the time value of funds, based on the depreciation method of compound interest and the relationship between mine production scale and equipment capacity and actual conditions of mines, the paper solves the optimized configuration problem about the type of main mechanical equipment and the quantity by applying integrated planning and Matlab software at the preliminary scheduling phase.This optimized configuration scheme brings better benefits for mining enterprises and provides a new idea about optimized configuration of equipment in capital construction phase of mine.

Key words: Compound interest method, Mine scale, Optimized configuration of equipment, Production capacity of equipment, Time value of funds
