Block caving: A new mining method arises Geoengineer.org

Jul 25, 2018  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.

Block caving method - SlideShare

Jul 14, 2014  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. This method is unlike sublevel caving, in that both the ore and the rock are normally involved in the caving.

Jul 06, 2012  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’.

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.

8.4.2a Block Caving. This method, which was developed in the U.S. after WW I, is well suited for mining in weak orebodies. Panels or blocks of ore are undercut. Once undercut, the weak orebody begins to cave under its own weight. The caved ore is drawn off through draw points.

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.

Block cave mining is an underground mass mining method that allows for the bulk extraction of large, relatively lower grade, ore deposits with substantial vertical dimension. In block caving, a large section of ore is initially undercut by drilling and blasting, creating a large unsupported roof that will start to collapse under its own weight ...

Block caving is a method which is used very successfully on large-scale mines exploiting massive orebodies or pipes. An undercut is developed beneath a block of ore incorporating the entire “footprint of the orebody,” the block having a height of 200 to 300m. In a pipe of diameter 1km SG of 2.5 a 200m block would contain 393 million ...

Jun 15, 2018  7. Sublevel caving. Sublevel caving is a method often evaluated in parallel with block and/or panel caving options. It requires multiple levels of development and ongoing ring blasting for production. Sublevel caving allows for a more selective extraction but typically achieves lower production rates than block and panel caving methods.
