BLAST FROM THE PAST THURSDAY - LET'S BLAST!!
This video from PAMining is an up-close look at the surface blasting process, showing the charging activities and finally blasting. As they say - don't try this at home!!
SHOWCASE MINE OF THE WEEK - UDACHNY DIAMOND MINE!!
Udachny diamond mine located in the Eastern-Siberian Region of Russia is currently the fourth deepest open pit mine in the world. The Udachny pit is currently 630m deep. Mining at the Udachnaya kimberlite pipe has been going on since 1971. The Udachny mine is owned and operated by Russia’s state-owned company Alrosa. The mine produced ten million carats of diamond per year until 2011. The probable contained diamond reserve at the open-pit was estimated to be 4.4 million carat
ONLINE MINING COURSE FOR NON-GRADUATES OR DIPLOMATS!!
This truly is a remarkable course for people that don't have a mining degree or diploma!! The information is extremely comprehensive and presented in a fun and visual way. You have the added benefit of doing the course even on your cell phone, and you have 365 days to complete the course. I highly recommend this course to people seeking a mining certificate!

It was designed for work in giant m
MINE PLANNING BASICS FRIDAY - HAUL ROAD EFFECT ON PIT LIMITS!!
A very basic illustration from Venkat Masabattula of the effect of introducing a haul road into the mine design. Note the effect on the average pit slope angle in the illustration bottom left. That's why I would recommend doing mine design iterations as well when selecting truck sizes for your fleet. Bigger trucks means wider roads means more waste for same ore... comments welcome!
BLAST FROM THE PAST THURSDAY - UNDERGROUND BLASTING!!
This clip from the Australian Centre for Geomechanics is a training video for underground metalliferous mine workers. The aim is to provide workers with the critical knowledge on drilling and blasting and to aid appreciation of the importance of these mining processes and their related hazards.
