Coal Strip Ratio Maps for the 2011 Victorian Coal Model Area

Ten geospatial strip ratio maps cover the 2011 Coal model area in Victoria, Australia, showing the ratio of coal tonnes to waste cubic metres. The maps were generated by the Department of Energy, Environment and Climate Action and are based on pre-mine topography. The dataset was last updated on 2026-04-09.

Use Cases

• Plan mining operations based on vertical strip ratios to different seam floors.
• Estimate overburden removal costs using the coal-to-waste volume ratios.
• Model resource extraction feasibility to specified depths (200m to 500m).
• Analyze historical mining impact by comparing pre-mine topography with current conditions.

Strengths

• Includes ten distinct maps for different geological targets (seam floors and depths).
• Based on a defined 2011 Coal model area and pre-mine topography.
• Available in multiple geospatial file formats (TAB, SHP, WMS, etc.).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The model uses pre-mine topography, and substantial coal has already been extracted, which may affect current applicability.
