Abstract
The development of methods and means to improve the efficiency of the mining facility is aimed at improving the efficiency of the use of raw materials concentrated in deposits of natural and man-made origin. This increase in efficiency is manifested through maximizing the content of commercial ore shipped for processing, creating prerequisites for increasing the shipment of commercial ore and increasing the productivity of the processing plant. Maximization of the content in commercial ore is based on the developed scheme of cyclical increase in the efficiency of resource potential use for the entire period of field development, supplemented by an improved method of current mining planning based on anisotropy of contents and dynamic conditions.
Highlights
IntroductionThe creation of prerequisites for improving the productivity of the processing plant is based on reducing mill downtime due to oversized ingress
The creation of prerequisites for increasing the shipment of commercial ore is based on the redistribution of dump trucks between overburden and ore cargo flows, which is possible from reducing the distance of overburden transportation as a result of the implementation of the "Fill – release – fill" cycle when working out ore warehouses in the external space
The separation of rock mass by grades with the release of conditioned ore at the "Deposit – quarry" levels occurs in the process of building a mathematical model of the Deposit during the development of the quarry project
Summary
The creation of prerequisites for improving the productivity of the processing plant is based on reducing mill downtime due to oversized ingress. For this purpose, segregation is used, as a result of which the dumps are divided by. Height into technogenic and technological zones with different granulometric composition of rocks. This division of dumps into zones is used for selective development of dumps with purposeful formation of cargo flows depending on the size of the pieces in the shipped ore and equipment at the receiving node of the processing plant
