Why is it recommended to avoid detailed estimation based on the smallest possible blocks?
Why is it recommended to avoid detailed estimation based on the smallest possible blocks?
- Smaller blocks reduce the number of equations to be solved.
- Detailed estimation based on small blocks is cost-effective.
- Smaller blocks increase the accuracy of grade estimation.
- Small neighboring blocks tend to have very similar grades. (correct)
How can dividing the linear dimensions of a block by 2 affect the estimation process?
How can dividing the linear dimensions of a block by 2 affect the estimation process?
- It multiplies the number of blocks to be estimated and equations to be solved by 8. (correct)
- It increases the accuracy of grade estimation.
- It decreases the number of blocks to be estimated.
- It simplifies the estimation process for complex deposits.
What is a suitable rule of thumb for determining the minimum size of a block?
What is a suitable rule of thumb for determining the minimum size of a block?
- Minimum size should be less than ¼ of the average drill hole interval. (correct)
- Minimum size should be directly proportional to the drilling grid dimension.
- There is no specific guideline for determining the minimum block size.
- Minimum size should be equal to the average drill hole interval.
