Hi All
A quick one: Grade tonnage curves.
1. Any good books/ articles that take you through the process (including
potential pit falls, no puns intended!).?
2. If I calculate a point grade tonnage curve (using the sample sections),
then one using e.g. 10x10 blocks then 30x30 until I reach the size of the
entire ore body, should I see a change in the ore body grade?
I can understand that my average mining grade is dependent on block size
(change of support, mining method mix etc etc), however the ore body grade
should be the same regardless of block size used.
Any feed back would be welcome.
Thanks
