UK Geoenergy Observatories Glasgow : express data release, mine water and environmental baseline monitoring boreholes at Cuningar Loop (updated June 2020)

Drilling of six mine water and five environmental baseline monitoring boreholes at Cuningar Loop was completed in December 2019 at the UK Geoenergy Observatory in Glasgow. This document and accompanying files provide an initial overview of the ‘as-built’ borehole infrastructure available for research and innovation

Mine water characterisation and monitoring borehole GGA05, UK Geoenergy Observatory, Glasgow

This report and accompanying data release describe the ‘as-built’ borehole GGA05 at the UK Geoenergy Observatory in Glasgow, as well as summarising hydrogeological testing and an initial geological interpretation. Mine water borehole GGA05 at the UK Geoenergy Observatory in Glasgow is screened across the Glasgow Main mine working void and overlying sandstone roof. The mine working is a water-filled void and initial hydrogeological indications from the test pumping are of a very high yielding borehole. Borehole GGA05 has ERT and DTS cables installed between the borehole casing and the rock wall and has a hydrogeological data logger installed within the borehole

Mine water characterisation and monitoring borehole GGA01, UK Geoenergy Observatory, Glasgow.

This report and accompanying data release describe the ‘as-built’ borehole GGA01 at the UK Geoenergy Observatory in Glasgow, as well as summarising hydrogeological testing and an initial geological interpretation. Mine water borehole GGA01 at the UK Geoenergy Observatory in Glasgow is screened across the Glasgow Upper mine working and overlying sandstone roof. The mine working is interpreted to be filled with a loosely packed mine waste. Hydrogeological evidence from test pumping indicates that the borehole is very high yielding. Borehole GGA01 has ERT and DTS cables installed between the borehole casing and the rock wall and has a hydrogeological data logger installed within the borehole

Mine water characterisation and monitoring borehole GGA08, UK Geoenergy Observatory, Glasgow

This report and accompanying data release describe the ‘as-built’ borehole GGA08 at the UK Geoenergy Observatory in Glasgow. They also describe initial hydrogeological testing completed after borehole construction and provide an initial geological interpretation. Mine water characterisation and monitoring borehole GGA08 at the UK Geoenergy Observatory in Glasgow is screened across the Glasgow Main mine working and overlying sandstone roof. The mine working is interpreted as a roadway with a void, mine waste and wood encountered. Initial hydrogeological indications from the test pumping suggest borehole GGA08 is very high yielding. Borehole GGA08 has ERT and DTS cables installed between the borehole casing and the surrounding rock, and a hydrogeological data logger installed within the borehole

Environmental baseline characterisation and monitoring borehole GGA06r, UK Geoenergy Observatory, Glasgow

This report and accompanying data release describe the ‘as-built’ borehole GGA06r at the UK Geoenergy Observatory in Glasgow, as well as summarising hydrogeological testing and an initial geological interpretation. Environmental baseline characterisation and monitoring borehole GGA06r at the UK Geoenergy Observatory in Glasgow is screened across a coarse sand and gravel in the superficial deposits. The borehole has proved to be low yielding on initial hydrogeological testing and has a hydrogeological data logger installed

Borehole GGA02, UK Geoenergy Observatory, Glasgow

This report and accompanying data release describe the ‘as-built’ borehole GGA02 at the UK Geoenergy Observatory in Glasgow, as well as summarising an initial geological interpretation. Mine water borehole GGA02 at the UK Geoenergy Observatory in Glasgow encountered the Glasgow Upper and Glasgow Ell mine workings and was screened across an interval interpreted as a completely collapsed Glasgow Main mine working and overlying sandstone roof. Unfortunately, grout entered the inside of the casing in the final stages of borehole construction, cementing up the screened section and resulting in GGA02 being repurposed as a cased, sensor testing borehole. New sensors can be tested inside the uPVC casing to 67.2 m drilled depth. Hydrogeological testing of GGA02 was not possible. Borehole GGA02 has a number of types of sensor cabling installed. Fibre-optic DTS cable is installed between the bedrock uPVC borehole casing and the rock wall with capability to work in passive (monitoring) mode to 72.65 m drilled depth. Fibre-optic cabling is also installed on the outside of the steel superficial deposits casing with the ability for use in active or passive mode. Electrical resistivity tomography cable with the deepest sensor placed at 85.58 m drilled depth is available for cross-borehole monitoring and imaging with the adjacent borehole GGA01

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

Long Term Operation of Renewable Energy Building

As part of a renewable energy project, a building was designed and constructed to demonstrate several renewable energy technologies at the Wind Test Center of the Alternative Energy Institute (AEI). The systems are passive and active heating, solar hot water, daylighting, passive cooling, and generation of electricity from a 10 kW wind turbine and 1.9 kW of photovoltaic panels, each connected to the utility grid through inverters. Since 1991, 16,900 kWh have been purchased and 31,300 kWh returned to the utility grid. A significant portion of the purchased power has been used in charging our electric van. The building does not have auxiliary heating or cooling systems powered by fossil fuels. A data acquisition system monitors building, exterior, and system temperatures as well as power outputs of the wind and PV systems. The data are sampled at 1 Hz and averaged each 15 minutes. Annual, seasonal and diurnal patterns are shown in graphical format. Temperatures for the coldest days of winter and hottest summer days are also presented
