Block caving method

Jul 14, 2014· Introduction The one u/g mining method that has the potential to rival surface mining in output and cost is block caving Block caving is the mining method in which masses, panels, or blocks of ore are undercut to induce caving, permitting the broken ore to be drawn off below If the deposit is overlain by capping or bounded by drawing the ore...

Definition of block caving

This sequence of mining is no longer widely used Today most mines use a panel system, mining the panels sequentially or by establishing a large production area and gradually moving it forward as the first area caved becomes exhausted The term 'block caving' is used for all types of gravity caving methods...

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...

Cave Mining Techniques

A variation of block mining is panel mining, which is a process that divides the ore into sections and extracts it in a similar fashion to block mining The difference between panel cave mining and block cave mining is attributed to the production process that moves sequentially along the length of the orebody so that only when one section of ....
