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. 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.

We haven’t been able to hold the conference since 2019 because of the Covid-19 pandemic, so I am delighted that we can meet again and drive forward development in the field of mine recovery in Wales. The conference will be held at Aberystwyth University on 12 and 13 September.

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.

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 Cwm Rheidol & Ystumtuen to see the latest metal mine remediation work and mine water treatment trials 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 September!
