Improving Evaluation Methods for Production Capacity and Life of Open Pit Diamond Mines

Аннотация

The article reports basic design parameters of open pit mines of ALROSA, as well as criteria and factors that govern the choice of production capacity of an open pit diamond mine under conditions of permafrost. The analytical relations and tables to calculate open pit mine life are presented, and the influence of the rate of the downward advance of an open pit mine on its capacity is demonstrated. The authors formulate key provisions for a paragraph of the national standard of RF enabling systematization of approaches to optimization of open diamond mining parameters.
