A self-propelled crawler and potato harvester was designed, with the terrain characteristics of both hilly mountainous areas considered, to address low degree mechanization, markedly harvesting rate, high labor intensity in areas. The could complete tasks digging potatoes, separating them from soil, transporting collecting a single operation. Finite element analysis conducted on major parts, su...

Abstract To improve mine production efficiency, reduce blasting costs, and meet the needs of capacity expansion, use an on-site mixing emulsion explosives truck for open pit iron ore deep hole step charging operation. This paper firstly briefly introduces process flow makes a detailed introduction to working principle control requirements each section production. Based on analysis basic adaptiv...

The main objective of this study was to synthesize scientific knowledge in order to characterize Whole Body Vibration (WBV) in open pit mining: sources, measurements methodologies and main effects on health. A review based on PRISMA Statement was done. Inclusion criteria were research on WBV in mining, published after 1990 and written in English. Thirty-three studies were included in the review...

One of the most challenging aspects in semi-mobile in-pit crushing and conveying (SMIPCC) system design is determining optimum depth at which to change from a purely truck-based haulage conveyor-based system. We used scenario analysis determine transition between truck shovel (TS) SMIPCC Traditional pit-limit algorithms were generate final pit limit on copper deposit, was then divided into four...
