Coal measure rocks tend to have anisotropic and elastically non-linear behaviour. Understanding this is a key to understanding strata behaviour in coal mines. This paper discusses which properties matter and how they can be measured. Some new test methods are introduced. The paper also discusses the relevance of geophysics in determining these properties.
