Better defined geological and hazard models for Bellahouston Park, Glasgow

Borehole records prove that the Knightswood Gas Coal (KDG) has been extensively worked in Bellahouston Park, Glasgow. In 2000, the British Geological Survey (BGS) undertook a commissioned research project for Glasgow City Council (GCC) to produce geological and hazard models related to abandoned mineworkings for Bellahouston Park (Rogers and Sowerbutts, 2000). The models identified some areas of the Park that have a thin drift cover and are crossed by the KDG outcrop*. These areas were classed as having the greatest likelihood of voids from mining of the KDG reaching the surface. Crown holes have previously developed within these areas. Other coal seams that crop out within Bellahouston Park did not appear to have been worked with the exception of the ?Banton Rider Coal in a small area beneath the Sports Centre and workings of the Pollock Stone Coal immediately to the east of the Park. Glasgow City Council would like the key, south-central area of the Park to be used for public events and need to constrain further the areas of greatest hazard immediately down-dip of the KDG outcrop, and also adjacent areas of least hazard on the up-dip side of the KDG outcrop. GCC commissioned BGS to devise a drilling programme of 13 boreholes, undertake stratigraphical logging of the cores during the drilling period, and subsequent revision of the geological and hazard models.
