Get MoreCaving methods can be used with any type of commodity since it is the geological and geotechnical context that is important. There are many parameters to consider but typically the orebody needs to be at least 100 m thick for cave mining to be economical. In the past, typical caving heights were 150-250 m.
Get MoreNo other method comes close to block or panel caving in terms of tonnages moved. For example, the worlds largest open stoping operation, Olympic Dam in Australia, produces in the region of 20,000-30,000 metric tons per day (mt/d), while Mount Isa produced around 20,000 mt/d from each of its
Get MoreMany large-scale open-pit operations have plans to progress into block caving operations over time, including Oyu Tolgoi and Grasberg. This mining method is typically used in situations where the orebody is both large and steeply dipping, and because of the depth below surface is
