Blasts were carried out in two different stopes at the -600 m level of the Shiling ore block
to contrastively investigate the blasting performance for different stemming materials.
9 Hornady branded .177 Black Diamond Steel SB's (3,000 count) ore block
anodized and manufactured by Umorex specifically for Hornady.
As the Zonge inversions consist of data points located in X, Y (for each section presented) and Z (being the northing of each section), the data were easily modelled using the Ore Block
Modelling module in Micromine.
In the second case where the ore block
has a small parcel of waste within it, the ore loss and waste dilution will be extremely high.
* The loading and hauling system is set up on the lower level for the whole ore block
. This possibly justifies the use of continuous mucking machines and/or electrically powered equipment, which would reduce ventilation requirements even further
