2019-8-19 · DEFINITION: A mining method which is applicable to low grade near -vertical metallic or nonmetallic deposits. Mining progresses downwards while the ore between sublevels is broken overhand with long hole uppers (fan -holes). The overlying waste rock (hangingwall or capping) caves into the void created as the ore is drawn off.

Sublevel cave mining: unearthing new opportunities

Historically sublevel caving has been perceived as a mining method that was prone to excessive dilution and poor recovery, and these issues negated the benefits. This negative perception, while probably not unwarranted in many cases, was rooted in practices based on early theories of rock flow which did not reflect reality ( Laubscher, Guest, & Jakubec, 2017 ).

Caving Mining Method Classification and Characteristics

2020-8-3 · Sublevel caving method is mainly used in the mining of iron ore deposits, most of which are newly built mines. At each stage, the surrounding rock should be artificially caved to form overburden rock. This mining method has the advantages of high strength, high efficiency, low cost, simple process, high mechanization degree, and safe production.

Design of a new layout for sublevel caving at depth

Abstract: LKAB has been mining iron ore with the sublevel caving mining method in northern Sweden for more than 60 years. Throughout the years, LKAB has improved this mining method to stay competitive in a tough international iron ore market. Improvements in drilling and blasting technology have helped LKAB increase the scale of sublevel caving and therefore decrease its mining
