Addressing the Challenges and Future Cave Mining

Addressing the Challenges and Future Cave Mining

Caving 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.
