FIGURE 5-12. The Layout Spreadsheet Columns D to G.
This spreadsheet is one of the few times in MINEWALL that you are required to
enter/manipulate text. Column A contains the labels Drain Level, Equilibrium Level, and Bottom
of Mine whose meanings are discussed in the MINEWALL report, Literature Review and
Conceptual Models. The latter label (Bottom of Mine) is initially displayed in Cell A20 on the
spreadsheet, but was manually moved upwards in Figure 5-12 because eight elevations were
considered sufficient to characterize the layout. You must move these three labels to their correct
position (elevation).
TIP: MINEWALL examines Column A of the Layout Spreadsheet for the first letter of each label.
Consequently, you do not have to re-type each label, but just its first letter in lowercase or
uppercase. For example, MINEWALL would identify b or B as Bottom of Mine.
Geochemical Units (Section 5.3.4) do not have to be physically continuous on the mine walls.
For example, Figures 5-11 and 5-12 show that 20% of Unit 2's exposed surface area lies below 920
m elevation and 80% lies above 940 m elevation.
After this information on mine elevations and exposure of units is completed, MINEWALL
