Description

The Coal Authority (CA) is commissioned by Cyfoeth Naturiol Cymru (Natural Resources Wales - NRW) to undertake engineering interventions for the remediation of pollution by abandoned metal mining at and around Nant y Mwyn Mine, Carmarthenshire. The interventions include the assessment of blow-out potential, and minewater treatment from the historic Deep Boat Level Adit. The Nant y Mwyn Mine is located to the north-west of the village of Rhandirmyn, Carmarthenshire, Wales, 10 km north of Llandovery, at NGR SN782438 (approx. postcode SA20 0PF). The works comprise installation of a borehole to intercept the Nant y Mwyn Deep Boat Level Adit. This will involve the advancement of up to 3No. rotary-drilled boreholes to confirm the location of the historic Deep Boat Level Adit. Work locations and provisional access routes are shown on drawing EV00483-010. Please see supporting documents for more detailed information.
