Mine water characterisation and monitoring borehole GGA04, UK Geoenergy Observatory, Glasgow

This report and accompanying data release describe the ‘as-built’ borehole GGA04 at the UK Geoenergy Observatory in Glasgow, as well as summarising hydrogeological testing and an initial geological interpretation. Mine water borehole GGA04 at the UK Geoenergy Observatory in Glasgow is screened across the Glasgow Upper coal and overlying sandstone roof. The borehole was drilled within an area of stoop (pillar) and room mine workings and is interpreted to have hit a coal pillar or partially collapsed pillar and a possibly fractured sandstone roof. It can be used for characterising and monitoring a fractured rock mass within a mine working area. Initial hydrogeological indications from the test pumping indicate that borehole GGA04 is high yielding. Borehole GGA04 has ERT and DTS cables installed between the borehole casing and the rock wall and has a hydrogeological data logger installed within the borehole.
