Types of Underground Mining Method Comparison

Caving Methods of Mining There are three distinctive methods of working large deposits that involve, in some way, the factor of caving. Slightly different names are in use, but those that are simple as well as descriptive are top slicing, sublevel caving, and block caving. In a discussion of these methods, three things must be borne in mind ...

Sub Level Caving - Rana Gruber

Sub level caving method allows working in parallel on different sub levels in the mine. This means that continuous excavation works can be on-going at one sub level without interfering with another. Project Sublevel Caving was carried out during the years 2009 and 2011, with a budget on 450 million NOK.

Sublevel caving is a relatively safe mining method since the operations take place in small areas at a time and are highly mechanized. The uniformly distributed nature of generally 5mx3.7m sublevel nature of drifts aids in the safety of this mining method. To increase the stability of drifts in competent rock is controlled by smooth blasting ...

Block Caving - Production and Mass Mining

Underground mass mining methods present several geotechnical challenges and risks inherent with block cave mining environments. Underground mining methods such as block, panel, and sub-level caving continue to be the primary choice for deeply situated massive orebodies, due to the high production rates and low operating costs involved.
