Block caving: A new mining method arises

2018-7-25  Block caving-A new mining method arises Block caving is a new alternative method of developing new mines or extending the operation of open pits. 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.

2020-3-24  Block caving is an underground mining method that uses gravity to exploit massive, steeply dipping orebodies located at depth, particularly those with disseminated mineralisation or that are low-grade in nature, but too deep to be extracted using open pit methods. Block caving also depends on insitu stresses and thehost rock’s ability to fracture in the correct fashion, although this can now be

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 a hanging wall, it caves too, breaking into the void created by drawing the ore.

Method for mining of rock or ore according to the

A method for mining of rock or ore according to the block caving principle, comprising driving, at several levels, substantially straight, parallel and horizontal drifts through the entire lower part of a block, choosing the distance between the drifts of each level so that remaining supporting pillars will cover at least 40% of the block area, undercutting the block from the drifts by blasting down the covering and
