Mining Plan Optimization Based on Linear Programming in Shirengou Iron Mine
Faced with the difficult situation of the joint operation of open pit and underground mining in transition period in Shirengou Iron Mine, a suitable linear programming mathematical model of mining plan was established and synthesis optimization results were obtained, which would increase the overall economic effect of the mining operation during the transition period, while the limited reserves and ore quality control were entirely considered. A pronounced economic benefit was achieved by the project optimization. This mathematical model can be widely used in mining process to control the quality and quantity equilibrium of ore output, comprehensive utilize some waste rock and optimize the mining plan.
