And Draw Cards module, used exclusively in block caving
environments, enables management of draw point extraction plans.
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.
Selection of preferred mining methods tended towards non-entry methods such as block caving
and sublevel caving, allowing high levels of automation, control and monitoring, thereby minimising the number of people required to work in potentially hazardous conditions.
Curtis Clarke MacLean's manager of sales & marketing told MM, "we are very excited about the machine and, although hoping it is never needed [because the whole point of block caving
is that it should cave without hang ups], we are eager for it to prove its worth once the cave is initiated.
The PEA envisages a combined openpit/underground block caving
mining operation operating over a span of 51 years.
Several Australian mines also rely on the inexpensive block caving
method of mining where large blocks of ore are undercut, causing the ore to cave in under its own weight and be easily scooped up.
Papers presented included JKMRC's recent work in block caving
conducted as part of a joint international caving study with US-based ITASCA Consulting Group.
