Newcastle Coal Measures is a major geologic formation in eastern Australia. Found in the Sydney Basin and Lachlan Orogen, this stratum is up to 1200 metres thick, consisting of dozens of different sub types. Formed between the Changhsingian and Wuchiapingian ages, around 256 to 252 Ma in the Permian.The historical strata temperature data were measured in operational coal mines and thus the depth of measurements is limited by the depth of the coal mining activity. The BSG UKGC data are derived from measurements in boreholes, which can be drilled to depths greater than the active coal workings and also in areas of unworked coal measures.In this paper, the mechanical behaviors of different lithological rocks of coal measure strata from Shanxi Formation in the eastern margin of the Ordos Basin, China, were investigated through uniaxial compression tests, and the deformation characteristics and failure modes of different lithological rocks were investigated.
