PLANNING AND MINE DESIGN IN OPEN-PIT MINING PROCESSES AT MINING ENTERPRISES

Abstract

This article presents the problem of short-term planning of open-pit mining processes and work shifts in mines and the design process of technological mine parameters in open mines is shown. The problem is mine and waste as well several problematic situations in truck parks and drop-off points are highlighted. Truck distribution is dynamic to permit each truck must be assigned multiple routes. The problem is deciding which one facades should be mined and specify the number of trucks, their routes and directions, and the amount of material transported by them to each drop-off point is satisfactory we can see the calculation ratio and their indicators as needed. The goals are to minimize the deviations starting with production targets, chemical grade and particle size range of each parameter control in each plant and reduce the number of trucks we can give examples of processes. To solve the problem, we developed a mixed integer linear objective programming model and tested it using real data from an iron ore mine. The results showed the proposed approach supports decision makers in sizing and allocation and in meeting the required targets of truck fleets and production and control parameters by ore processing plants in a day-to-day scenario such as low availability the flexibility of shovels and trucks, ore quality, and the need to increase production have been widely discussed.
