Strip Ratio Maps
The following ten strip ratio maps were generated accross the 2011 Coal model area:
to Yallourn seam floor;
to Morwell 1a seam floor;
to Morwell 1b seam floor;
to Morwell 2a seam floor;
to Morwell 2a seam floor;
to Traralgon seam floor;
to 200m depth;
to 300m depth;
to 400m depth; and
to 500m depth.
Maps show vertical striping ratio expressed as coal tonnes to waste cubic metres. Seam floor maps are calculated to the floor of the specified seam (or lowest split); or lowest overlying seam if this seam is absent. Depth maps are calculated to the lowest seamfloor that is shallower than the specified depth. The model is based on a pre-mine topography and substantial coal has already been extracted.
