Abstract

There are some limitations and constraints in application of algorithms developed to optimize open pit limits. Therefore, it is normal to develop new algorithms to decrease existing limitations and increase their capabilities. In this paper, the key group concept which mainly use for stability slope analysis is used to develop a new algorithm named “KG-PLO” to optimize open pit limits. The KG-PLO is implemented on an especial type of the economic block model of the mining area. The algorithm can present the true optimal limit because it is rigorous and have a mathematical proof. Since the KG-PLO enjoys a sequential procedure, the logic iteration is not too much. A computer program in Mathematica media is written to implement the KG-PLO algorithm.
