Features of using equipment for in-pit crushing and conveying technology on the open pit walls with complex structure

Purpose is to substantiate the use of an in-pit crushing and conveying technology at open pits with complex structure working zone, which technological includes inclined steeply conveyors for improved economic efficiency mineral mining deep levels. Methods. The study applies a method including: technical-economical analysis practice enterprises, experience using units concentration plants pits; mining-geometrical in terms pit sections – identify zone wall its features along depth; structural developments improve design steeply-inclined conveyor; simulation modelling processes select optimal technical solutions. Findings. Basing on performed studies, it has been identified that transfer new trend technology, considering pit, rather prospective. In this context, expedient or deep-trough sites inclination angle 10-18°; case 30-36°, recommended conveyors. Originality. For first time, relation between formation complexes identified.
