Annotation:

The influence mechanism of the cutoff grade of iron in ore on the current overburden ratio for steeply dipping iron deposits at stage of operation of open cast is defined. Account taken of this influence is obligatory for determination of possible factory's profit from concentrate realization. The analysis of the results in situations of operated increase and fall of the cutoff grade is made in terms of fluctuation of concentrate prices at the market. The analysis is illustrated by an example of the typical layout of a working zone of an opencast.
