Dr Pete Brabham (FLEXIS, Cardiff University) will discuss the potential of utilising Geothermal Heat from ground water in the abandoned mines of South Wales. South Wales has somewhere between 1000-2000 abandoned coal mines from 250 years of coal exploitation.
The deeper, larger shaft mines when in operation continually pumped out water to stop flooding the 100s of miles of underground tunnels. When the mines were closed and abandoned the pumps were shut off, the mines gradually flooded. The question is that what is the temperate of the water in the mines today and can it be utilised for green geothermal energy?
Bridgend County Council commissioned a multi-disciplinary team from the FLEXIS project at Cardiff University and BGS to investigate this geothermal potential at Caerau in the Upper Llynfi Valley. In Autumn 2017 a 250m deep borehole was drilled into the mine workings in the heart of the village. This talk illustrates how the borehole location was determined and the hydrogeological results of the study.
