Significant upside opportunity - Newcrest believes it will be able to unlock significant value from the deposit by applying its unique technical expertise in block caving
, operations optimisation and selective processing.
"It makes more sense to do sub-level caving method rather than block caving
for Silangan," Austin said.
This Indonesian operation is expected to deliver less than half the amount of copper it produced in 2018, as it transitions from the end of open-pit mining to additional contributions from underground block caving
As for the local miners, to overcome the production costs mining is mostly done using block caving
is a mining method in which blocks of ore are undercut to induce caving, allowing it to break up and be drawn off, pulled by gravity.
The so-called induced caving mining method is a newly improved underground mining method as a combination of the block caving
mining method (Figure 2(a)) and the sublevel caving mining method (Figure 2(b)) essentially.
Some scholars also extensively examined the block caving
MacLean, a former Inco employee who worked in Sudbury, developed drawpoint obstruction clearance machines for block caving
rigs, including blockhole jumbos in the late 1970s.
Famorca, 81, said the tailings dam serves Philex's original block caving
operations at the Padcal mine in Itogon, Benguet.
Since retiring he has been involved in block caving
projects for BHP Billiton, Anglo American and Rio Tinto.
A component of our next drilling program will be to further expand the higher grade core while also expanding the larger system which is believed to be amenable to the low-cost block caving
Researchers will work on sensing technology for use in block caving
to measure the underground area containing minerals and the size and shape of these deposits.
