The features of three- and four-tier internal dumps capacity calculation with the additional capacity preparation in the dump tiers

摘要

The paper deals with the task of increasing the volume of rock placed in the internal dump. For that it is necessary first to analyze the existing technology of internal dumping, and then to determine the height of rock tiers being cut in the transport area. Analyzing the mining on the southern pits of Kuzbass it was found that now mostly three-tier dumps are piled. But for placing the extra volume of rock in the internal dump it will be required to pile dumps with more than three tiers.
