I was just pondering how much cover would have to be removed to get to the top of ore
176,000sq m
X 420m cover
X 3 sg
= 221,760,000 tons
Sandvik 663 can carry 63 metric ton
= 3,520,000 loads
Comparing that with the top of the ore body first level 350m deep you can see there is an awful lot of ore to come out 2,933,000 loads
