Block Caving Method Of Mining Block Caving

Block Caving Mining Magazine - REDPATH MINING

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 the host rock's ability to fracture in the correct fashion, although this can

Hydraulic Fracturing & Block Caving Systems |

Block caving method involves mining deep, large and low grade ore bodies whereby a large section of rock is undercut, creating an artificial cave. High pressure pre-conditioning systems are required to increase production rates related to block caving. Feel free to reach us, let us assist you!

15.06.2018· 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.

24.07.2019· Block caving is the intended mining method for several significant copper projects under development. Key competitors involved in the major block cave copper projects include Rio Tinto, PT-Freeport Indonesia (PT-FI) and Codelco. The five largest projects that have either commenced production this year or are forecast to commission over CRU's forecast period will use block cave mining. These

11.03.2018· Some block caving operations have mining costs that are less than those of open pit mining operations, which is considered to be the cheapest mining method. Due to high dilution and low recovery, block caving should be used for large, steep, and low-grade ore bodies. Due to the low selectivity of the block caving method, it is suitable for ores

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.

Block caving mining method with Elfen

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. To allow the cave to propagate, broken ore

The Block Cave Mining Method - UKEssays.com

20.06.2018· Block caving is an underground mining method applicable to the extraction of low-grade, massive ore bodies with the following characteristics: large vertical and horizontal dimensions, a rock mass that will break into pieces of manageable size, and; a surface that is allowed to subside. These rather unique conditions limit block caving to particular types of mineral deposits. Block caving is
