Stress-Dependent permeability data for samples of the Glasgow Main coal and the overlying mudstone and sandstone from the UKGEOS research borehole GGC01. Associated XRD mineralogy, Helium Porosity, bulk and matrix densities are also included. Samples and data are derived from the UK Geoenergy Observatories Programme funded by the UKRI Natural Environment Research Council and delivered by the British Geological Survey.

The UK Geoenergy Observatories (UKGEOS) Glasgow 3D coal mine model outputs, created by the British Geological Survey, provide a semi-regional overview of the depth and extent of surveyed and probable coal mine workings, plus stone and coal roads surveyed within the mines. The model allows users to visualise the surveyed and probable coal mine workings to be found beneath this part of Glasgow, applicable at a scale of around 1: 25,000 to 1: 10,000. The data is supplied as grids, triangulated surfaces over a 5 by 4.15 km area, with the depth range to around 300 m below Ordnance Datum. The mine extents are ‘cut out’ of the UKGEOS Glasgow post-drill bedrock model. This model describes both surveyed (recorded on mine abandonment plan) and probable coal mine workings. An area of probable workings has been updated to account for the results of drilling borehole GGC01.

The UK Geoenergy Observatories (UKGEOS) Glasgow bedrock model outputs, created by the British Geological Survey, provide a semi-regional overview of the depth and extent of bedrock lithostratigraphic units, coals and faults. The model allows users to visualise the likely subsurface sequence to be found beneath this part of Glasgow, applicable at a scale of around 1: 25,000 to 1: 10,000. The data is supplied as grids, triangulated surfaces and shapefiles over a 5 by 4.15 km area, with the depth range to around 350 m below Ordnance Datum. This model describes an interpretation of the bedrock geology after the UKGEOS Glasgow boreholes had been drilled, the results of the nine UKGEOS boreholes that penetrated bedrock have been incorporated.

UKGEOS and Core Sample Analysis. Geomechanical testing was performed to determine triaxial compressional strength, tensile strength, frictional strength and permeability of sandstones, siltstones, mudstones and coals from eleven depth intervals within the GGC01 borehole, UK Geoenergy Observatories (UKGEOS), Glasgow, United Kingdom. Frictional strength tests were also performed on cuttings samples of sandstones, siltstones, mudstones and coals from the GGA08 borehole, Glasgow, United Kingdom. In total twenty-three tensile strength tests were performed on ten sampled intervals, and seven porosity measurements pre-and post-failure were taken. Nine triaxial compressive strength tests and twenty-one frictional strength tests were performed, with permeability measured both before and after failure or shear respectively. From compressive strength tests we also determined the Young’s modulus and Poisson’s ratio. Results of X-Ray Diffraction are also included in the dataset.
