Introduction
For simplicity, a coal measure is a series of layers formed from a repeated cycles debris accumulation and cover by sedimentary deposits. As an illustration, the description of measure versus layer, for CSG applications in AFA, is given below:
In AFA, layers within a coal measure can share properties to an extent defined by the user. Properties, by measure, are completely independent from any other measure.
As an example, the image below shows an exposed section of the Illawarra Coal Measures with several layers.
