Abstract

This study proposes innovative technological schemes for openpit mining to reduce costs by minimizing transportation distances. The schemes involve dividing the mining front into sections, mining sections with overburden benches that undercut the mineral layer, and mining benches with the placement of rocks in internal dumps and the advancement of the dump front after bench mining. The research identifies optimal mining block schemes and parameters that maximize productivity. Additionally, the study highlights actual losses in production time due to organizational set and provides strategies to achieve combine efficiency.
