Column Explanation:
1) Month of the year
2) Estimated percentage of the annual production during the month.
3) Calculated as 1,350,000 x Column 2
4) Calculated as{(Column 3 x 2,000 x 0.02)/62.4/43,560)
5) Monthly values from Table 1 Column 4
6) Sum of Column 4 and Column 5
7) Lagged stream depletionf from monthly values in Column 6 using AWAS and a SDF of 88 days
Note:
Since mining operation is considered dry-mining with an impermeable layer moisture content in
mined aggregate is considered at 2%.
