Definition of block caving

The term block caving is used for all types of gravity caving methods There are three major systems of block caving and they are differentiated by the type of production equipment used 1 The first system based on the original block cave system is the grizzly or gravity system and is a full gravity system wherein the ore from the...

Underground mining hard rock

Bulk mining methods Block caving is used to mine massive steeply dipping orebodies typically low grade with high friability An undercut with haulage access is driven under the orebody with drawbells excavated between the top of the haulage level and the bottom of the undercut The drawbells serve as a place for caving rock to fall into...

Mar 09 2018 0183 32 As compared to other mining methods sublevel caving allows for a quicker and less expensive mining process However sublevel caving leads to greater dilution and is therefore used for lower ore bodi The costs for sublevel caving range from 5-8 /tonne Block Caving Block caving is the logical step-up of sublevel caving...

Block Caving

Block caving is an underground hard rock mining method that involves undermining an ore body allowing it to progressively collapse under its own weight It is the underground version of open pit mining In block caving a large section of rock is undercut creating an artificial cavern that fills with its own rubble as it collaps...

Sublevel caving

Sublevel Caving is one of the most advanced mining methods This method is usually undertaken when mining the orebody through an open pit is no longer economically viable In Sublevel Caving mining starts at the top of the orebody and develops downwards Ore is mined from sublevels spaced at regular intervals throughout the deposit...
