Why this year’s MineXchange Conference cannot be missed if you work in mine recovery in Wales

MineXchange is a two-day conference that develops relationships between people who work in mine recovery in Wales. It will be held on 27 and 28 February 2023 at Aberystwyth University.

We want to help people from academia, industry and the public sector to make new links and to support innovation by sharing knowledge and experience. The conference will also look at opportunities to commercialise damaged mine environments.

I am delighted that we can meet again and drive forward development in the field of mine recovery in Wales. The conference – which is arranged by Natural Resources Wales, with the Coal Authority – will be the place to learn about developments in mine recovery and cutting-edge methods and technology.

We had planned to hold the conference in September 2022. This would have been the first time the conference would have been held since 2019. While Covid-19 had stopped the conference going ahead until 2022, we postponed the 2022 conference as a mark of respect following the passing of Her Majesty Queen Elizabeth II.

The day will include a range of presentations and case studies provided by experts in the field from industry, the public sector and academia.

The second day – which delegates do not have to attend – is a fieldtrip led by Natural Resources Wales and the Coal Authority to Frongoch-Wemyss to see the latest metal mine remediation work being carried out in the area. Transport will be provided.

Registration is free of charge and essential to attend.

Accommodation can be booked directly from Aberystwyth University by emailing https://bookaccommodation.aber.ac.uk/.

I am very excited that we have managed to secure such high-quality speakers who will present their work on a wide range of topics. But don’t take my word for it, have a look at the agenda below – and see you in Aberystwyth in February!
