PLANNING OF A REGIME OF STRIPPING WORK WITH REGARD TO THE OPEN PIT PERFORMANCE BASED ON MINERALS
On the example of an imaginary extended deposit, a method of choosing the direction of mining operations in its open pit was developed, providing work for it with the minimum current ratio of overburden and a maximum output of ore. It is shown that the work of an open pit with a minimum current ratio of overburden is possible only in case of the equality of the current stripping ratio in all areas of the field. The algorithm for identifying and averaging of operational stripping ratios using graphs V = f (P), first proposed by A.I. Arsentiev, was developed: the selection area of operation regimes of mining was limited. A new technique to choose the direction of mining operations in the open pit is different from the well-known view of the interactions of mode of stripping and performance of an open pit by minerals.
