Question
Task D) Oil Shale, Coal Resource Estimate and Environmental Water Constraints
Estimate the volume of the geological oil shale and coal resource based on the geological modelling that has
been undertaken for the Windy Hill region (Appendix 2). While this will be only an initial rough estimate,
assumptions should be detailed, such as the economic depth of the resource, mining technique(s) employed
and minimum oil shale and coal seam thicknesses. Separate the coal into bituminous and anthracite.
Estimate the tonnage to be removed and include an overall tonnage for each rock type. This includes
researching typical densities for the material removed.
Identify areas that are not permissible to mine due to the presence of ground water aquifers that directly flow
to the overland water areas.
Consider the role that rehabilitation takes and outline the key components of rehabilitation and when these
components of rehabilitation should occur.
