Inside block caving: the deep mining method of …

Block caving is a mining system which involves undermining an ore body and then allowing it to collapse under its own weight, a process that opens access to deeper deposits.

WhatsApp: +86 18221755073

Mining Method

The most viable way to recover the ore body is by a well-established underground mining method called block caving. Block caving is safe, environmentally sound, and cost-effective for mining a large, deep orebody. In block caving, a large section of ore is initially undercut by drilling and blasting, causing it to collapse under its weight.

The design & operating philosophies of panel vs block …

It is common practice today to use 'block caving' as a generic term to describe both block and panel caves, however this erroneous use of terminology is also reflected in modern cave design. Although both block and panel caves are variants of caving mining methods, their development and production philosophies are fundamentally different.

Block caving method | PPT

The block caving mining method involves undercutting masses of ore to induce caving and allow the broken ore to be extracted below using gravity. It is unlike sublevel caving in that both ore and rock cave together in a columnar fashion to the surface, resulting in massive subsidence. Development for block caving is extensive due to the need ...

Block caving mining method with Elfen software, explained …

Block caving is a mining method that relies upon natural forces to break the rock. The cave is initiated by an undercut where a large area beneath the mining block is removed; gravity induced stresses then develop within the rock, causing it to fracture. The fracturing process is progressive and affects the entire rock mass overlying the undercut.
