Block Caving- The cost-effective alternative to conventional mining | ACIM
Planning to dig a mine or even to extend the longevity of an existing mine, many mine planners now have a great alternative method of mining to use- Block caving. Sometimes, deposits are too deep to use economical methods like open pit techniques to extract resources. Some other times the value of the deposit is not sufficient enough to justify more conventional and costlier underground mining methods. However, under suitable conditions, block caving provides so many advantages that it is being considered for many projects like the copper mines in the Northparks in Australia. Block caving is a mass underground mining method which allows bulk extraction of lower grade, large, ore deposits that have a much longer vertical dimension. When using block caving method, a huge ore section is undercut by blasting or drilling. This creates a substantial unsupported roof which starts to collapse due to its own instability and weight. The large broken ore then starts breaking apart bef
