Block Caving Method Of Mining Block Caving

mining and mines Block Caving

Block Caving Block caving is an inexpensive bulk mining method where the ore is drawn by gravity and which is suitable for ore bodies which are low grade and are consistent in their grades Depending on how the ore is broken there are three block caving systems 1) The Grizzly system for fine material 2) the slusher system for coarser material

Block caving method Technological Resources Pty Ltd

A method of block cave mining comprising excavating undercut tunnels (21) at an undercut level drilling undercut blast holes (25) through the undercut tunnel roofs and setting and detonating explosive charges in those holes to blast rock above the undercut tunnels to initiate the formation of broken rock caverns (26) above the undercut tunnels (21) excavating extraction level tunnels (22) at

Method for mining of rock or ore according to the block

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

Cave Mining Techniques

Block caving is a large scale mining method that is particularly useful for mining low grade or disseminated ore bodies which are at too great a depth to be exploited through open cast mining This mining technique gets its name from the layout of the mine which divides the ore into large sections or blocks

Definition of block caving Mines Minerals

Definition of block caving A general term that refers to a mass mining system where the extraction of the ore depends largely on the action of gravity By removing a thin horizontal layer at the mining level of the ore column using standard mining methods the vertical support of the ore column above is removed and the ore then caves by gravity
