Abstract

Abstract: In order to solve the problem of high loss and dilution of ore by using the pillar-less sublevel caving method, the formation of caving body is numerical simulated, the shape of caving body is determined. The moving laws of the internal ore-rock of caving body is studied by monitoring particle displacement in the ore drawing process.The study results of the paper has strong guiding significance for the actual production of mine.

Key words: Pillar-less sublevel caving method, Ore drawing, Caving body, Numerical simulation
