Underground Mining Methods

Sublevel Caving Sublevel caving is usually carried out when mining of the ore body through an open pit method is no longer economically feasible. Mining now proceeds underground, underneath the open pit. At first, both a raise and a network of tunnels are.

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, ).

Cave mining : advancing cave mining to meet …

 · Sublevel caving is a method often evaluated in parallel with block and/or panel caving options. It requires multiple levels of development and ongoing ring blasting for production. Sublevel caving allows for a more selective extraction but typically achieves lower production rates than block and panel caving methods.

Types of Mining Methods

 · Sublevel caving is a large-scale mining method, suitable for large ore bodies with a steep dip. The setup is similar to long-hole stoping except loft raises are not required. Also, mining starts at the top of the ore body and progresses downwards in a safe sequence.
