THE OPTIMAL BLOCK SIZE IN THE BLOCK CAVING MINING METHOD

During recent years in underground mining the block caving method for low grade and large scale deposits has shown a growing rate of application This method is very cost effective and economically affordable The dimensions of blocks are one of the most important parameters which should be taken into account since it has been proved to have a great deal of effect on technical issues such as

Block Caving ABC 123 Testing Site /

Block Caving This method which was developed in the 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 As the ore is drawn off the orebody will continue to cave under its own weight This process will continue until all

The Block Cave Mining Method

· 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

How are diamonds mined by Petra Petra

Block caving Cave mining both block caving and sub level caving which is currently used at Petra s underground mines in South Africa is a well established and safe mechanised mining method that was first introduced at Kimberley South Africa in 1951 It is now used extensively as an underground mining method as it allows for the bulk mining of large orebodies and enables a higher ore

Numerical modeling of influence parameters

· Block caving mining method Block caving is an underground mass production system of ore extraction which under favorable conditions gives lower mining costs than any other underground method However it requires relatively large capital expenditure in terms of preliminary development and infrastructure establishment Block caving is suited to massive orebodies with a well disseminated

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

Determination of Optimum Drawpoint Layout in Block Caving

Among underground mining methods block caving is typically a large scale method and one of the few economical techniques for the extraction of deep and large low grade material Castro et al 2012 however caving is very challenging because its operational complexity is largely affected by the initial design which has limited flexibility once the drawpoints have been set Drawpoint location

Caving Methods Mineral Production Activities

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 a 200m block would contain 393 million tonnes of ore Thus the ratio of costly development to
