We call it a Blockholer, you may know it as a secondary reduction drill, but either way it comes down to the same thing… a critical tool for making sure the ore flows in underground mining.
The current issue of the Volvo Construction Equipment magazine features a story on a research initiative being undertaken in Sweden to study the benefits of an all-electric fleet of quarrying machines. The multi-year (out to 2018), multi-partner (private sector, academia, national energy agency) project is expected to document a 70% decrease in energy consumption and a 50% decrease in GHG emissions.
At MacLean, we’re big fans of block and panel caving animations like the nifty ones for Resolution Copper, Northparkes, and New Afton that cleverly depict the sequence of steps required to create these underground rock factories.
Thumbs-up to the Minerals Industry Safety and Health Centre at the University of Queensland in Australia for their development and free release of an app to measure Whole Body Vibrations for miners in the underground environment (“WBV” is the app name).
