Sublevel Caving Block Caving Longwall mining method includes drivage of two long roadways in coal and joining them at the end by a perpendicular drivage forming a face. Longwall General Layout.

Sublevel caving ScienceDirect

If we possess exact and detailed information about the gravity flow of the blasted rock in the sublevel and if we carry out an exact planning and control especially of the drilling and loading operations, we can turn the modified sublevel caving method into an effective, cheap and above all a safe mining method. 2.

Underground Mining Methods and Equipment is intended as both a course and a technical reference for an audience of engineers, operators, contractors, consultants, regulators, practising geoscientists and students in the mining sector. The course provides a comprehensive introduction and reference for those who require a solid grounding in selection, design and development of mining methods and

Sublevel caving: Engineered to Perform Elexon Mining

Source: Mining Magazine, September 2013. Sub-level caving is a highly efficient, top-down, underground bulk mining method. Recent developments in sub-level cave mining have advanced the understanding of the technique and its production performance, which allow it to now be considered as a highly viable alternative to open stoping and, in some cases, even to block caving.

Sub Level Caving PHDessay

The wall caving is induced by mining the ore in controlled sequence, usually from hanging wall to footwall and from top to bottom. Sublevel caving is often used in conjunction with surface mining. Sublevel caving extracts the ore via sublevels, which are developed in the orebody at regular vertical spacing.

Sublevel Caving Technique: Simplicity and Low Cost

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.

Sub-level caving success at Syama Mining Magaine. Sub-level caving is an advanced and highly efficient low-cost bulk underground mining method that provides early access to ore. Mining commences at the top of the deposit and develops downwards. Ore is mined from sub-evels spaced at regular intervals throughout the deposit.

2021-3-18  A feasibility study on MCQ is expected soon, but the 2019 prefeasibility study outlined a circa-$1 billion sublevel caving (SLC) project able to generate an internal rate of return of 15%. Using the SLC mining method, a production rate of 6.2 Mt/y was estimated, with a forecast life of mine of 23 years.

2021-3-19  Sublevel caving is based on gravity flow inside a broken-up rock mass containing both ore and rock. The rock mass is first fractured by drilling and blasting and then mucked out through drift headings underneath the rock mass cave. It qualifies as a safe mining method because the miners always work inside drift-size openings.
