Sub-level Caving - Polymathian

Sublevel caving (SLC) is classed as a cave mining method, even though the energy source for breaking ore rocks is through drilling and blasting, i.e. explosive energy. In SLC, the overlying low-grade, or mainly waste cap rocks, then naturally cave above the blasted ore rock, but utilising the energy generated by induced stress and gravity to ...

slice. Mining continues upwards towards the surface until the ore body is depleted. 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 made.

Sublevel caving techniqueSimplicity and low cost are the essence controlled drilling and blasting. Sublevel caving is in many respects simple. It can be used in orebodies with very different properties and it is easy to mechanize. In sublevel caving, ore is developed from a series of sublevels spaced at regular intervals throughout the orebody.

Caving methods are defined as those associated w ith induced, controlled, massive caving of the ore body, the overlying rock, or both. Th e exploitation workings in caving methods are designed to collapse, with intentional caving of the ore and/or host rock. The three major caving methods are: • Longwall mining • Sublevel caving

Underground Mining Methods and Equipment

Production scheduling in underground mines is still a manual process, and achieving a truly optimal result through manual scheduling is impossible due to the complexity of the scheduling problems. Among the underground mining methods, sub-level caving is a common mining method with a high production rate for hard rock mining. There are limited studies about long-term production scheduling in ...

Jun 14, 2019· This mining method can be applied to numerous types of ore bodies with inclination from horizontal to vertical. If ore body is narrow its inclination should be steep in order to apply the method. It is desirable that ore is strong enough to minimize support requirements for sublevel drifts, while surrounding rock mass should be prone to caving.

Underground Mining Methods - MineralsEd

This method is usually considered as an alternate to sublevel caving when a lower dilution method is needed and where the rock is fairly competent. The production for a mine using sublevel stoping can range from 15- 40 tons/employee-shift, while one stope can produce greater than 25000 tons per month.

Types of Mining Methods | Sell Side Handbook

The sublevel caving (SLC) mining method has evolved over the last 100 years. The method was first used in the early 1900s in soft iron ore mines in Minnesota and Michigan, USA (Hartman and Mutmansky, 2002) . It represented an evolution from top slicing, but was initially highly labour intensive and required heavy timber support
