Abstract

The cutoff grade problem is an important research challenge and vital optimization task in the yearly operational planning of open pit mines due to its combinatorial nature. This results from the fact that it is influenced by economic parameters, the capacities of stages in the mining operation, the mining sequence, and the grade distribution of the deposit. Essentially, it asserts that the dynamic cutoff grade during any given period is a function of the ore’s availability and the needs of the mill in that period. Consequently, the cutoff grade strategy and extraction sequence should be considered simultaneously. With these factors in mind, various attempts have been made to develop a computerized procedure for the extraction sequence of open pit mines. None of the resulting approaches appear to enjoy widespread acceptance because of the numerous variables involved. A new model has therefore been proposed to overcome this shortcoming. This model solves the problem in three steps:
