14-2-2020· The role of block caving Although the caving mining system was initially used for shallow orebodies, it has recently been applied at depths of 2km underground. According to Suorineni, “caving heights have also increased drastically from about 200m to 500m”, creating so-called ‘super caves’.“There is insufficient experience caving in these environments,” he adds, which is a ...

Mining Methods: Block Caving | Geology for Investors

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 collapses.

Underground mining (hard rock) - Wikipedia

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.

Block Caving - Mining Fundamentals

Block caving is a gravity-based underground mining method that involves breaking up the rock mass located at depth into pieces. This method is particularly suitable for low-grade minerals or with disseminated mineralization. “Block” refers to the mining layout, which divides the ore bodies into blocks and large sections.

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’.

mining and mines: 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 and 3) the LHD system for very coarse material.

Block caving methods are used for mining of massive ore bodies where ore is easily caved, not prone to oxidation and has low clay content. Subsidence of the surface is inevitable side effect of these methods. Key point is to create undercut large enough to induce stresses that will cause failure of the above laying rock mass, i.e. caving.
