block caving and primary crushing Solutions Just Right For You

Block cave mining is a widely employed mining method around the world due to its low operating cost One of the key factors that affects block caving mine's productivity is fragmentation accordingly significant efforts have been made and are currently being made to study fragmentation processes including the use of numerical modelling and remote sensing Jaw crushers are typically used as primary crushers or the first step in the process of reducing rock They typically crush using compression The rock is dropped between two rigid pieces of metal one of which then move inwards towards the rock and the rock is crushed because it has a lower breaking point than the opposing metal piece

Primary Sources E-Books Large ore bodies of lower grade can be mined with the block caving method so called because mining occurs sequentially in segments or blocks 200 to 500 feet (60 to 150 meters) wide A series of railroad tunnels is first constructed under the ore to be mined Crushing

Sublevel Caving can be used in orebodies with very different properties and is an easy method to mechanize This method is normally used in massive steeply-dipping orebodies with considerable strike length and usually has a high amount of dilution and low recoveries Thus Sublevel Caving is usually used to mine low-grade low-value orebodies
