Environmental Engineering PhD: Digital Twins for Reusing Former Mine Sites

Environmental Engineering PhD: Digital Twins for Reusing Former Mine Sites

Quick Decision

This project would build two digital twins to compare reuse futures for post-mining landscapes: a surface-mine setting in South Wales and an underground setting on the Isle of Portland. Its six advertised work packages connect international case review, remote-sensing and laser-scan surveys, model construction, local sustainability appraisal, an adaptable optimisation toolkit and an assessment of decision impact. The research question is practical as well as technical: how can reuse decisions support local resilience while respecting landscape conditions and environmental protections?

Feasibility turns on site access, usable survey data, and a clear, testable definition of each twin. The public project materials do not specify exact sites, model update frequency or validation criteria. Funding and application dates also need written clarification: the award page gives conflicting labels for the £21,805 stipend and lists references for 8 January 2027, while general guidance lists 15 February. Until admissions confirms the operative dates and 2027/28 amount, plan against the earlier reference deadline and do not treat the stipend figure as settled.

Research Problem and Doctoral Work

What is unsolved and why it matters

Mining can end when deposits are exhausted or no longer economic, leaving infrastructure, natural capital, environmental liabilities and communities that may have few alternative sources of employment. Reopening marginal mines, maintaining legacy operations and closing exhausted sites all create different land-use choices. The project argues that existing decision strategies are inadequate for choosing reuse options that diversify local economies without disregarding landscape conditions and environmental protections. Its longer-term ambition is to make mine-transition decisions more informed from industrial planning through development and eventual closure. The project description

The two primary case contexts are deliberately different: an overland/surface mining landscape in South Wales and an underground mining landscape on the Isle of Portland. Wider comparisons may include South West England and the Peak District. A “digital twin” is described as a virtual replica used to model reuse scenarios and test alternative futures before costly or socially and environmentally damaging decisions are made. The public description does not specify whether the twins will be static, periodically updated or linked to live monitoring data, nor does it name the exact sites. Those are central scoping questions, not details to assume.

Work, methods, and potential outputs

The advertised doctoral work includes six connected tasks:

1. Survey international examples and consult on reuse of old mines, quarries and tips for resources, environmental restoration, tourism or cultural heritage, innovative manufacturing, and research industries.
2. Carry out field surveys using remote sensing and laser scanning to build representations of the UK surface and underground case landscapes.
3. Construct the digital twins with support from the Deep Digital Cornwall environment and test how the landscapes could be reconfigured for alternative uses.
4. Assess the sustainability potential of alternatives using appropriate criteria and local consultation.
5. Develop an optimisation toolkit intended to adapt across multiple scenarios.
6. Evaluate how the approach could affect decision-making for industrial extraction and post-extractive resilience. Official project description

A useful research plan would distinguish the twin’s data model from its visual interface: set a system boundary; document how survey, environmental, infrastructure and community data are sourced and updated; state uncertainty; and define validation against site observations or planning decisions. Recent mining-twin research points to fragmented deployments, interoperability and scalability challenges, and the need to define model dimensions and boundaries before implementation. Research specifically on post-closure landscapes is less developed: a 2023 ESG paper notes sparse documented use in deconstruction/closure, while a Japanese former-mine simulation tests one data-centre reuse case and calls for broader, longer-term analysis. These are adjacent precedents rather than evidence that a validated landscape-scale reuse twin already exists. Mining digital-twin review, mining twin design framework, digital twins and mining ESG, former mine data-centre simulation

Potential doctoral contributions include comparing what can be represented and validated in an underground versus a surface setting; building transparent sustainability criteria that combine ecological limits, infrastructure, local priorities and economic diversification; and testing whether scenario tools change how stakeholders make decisions. The project explicitly advertises an adaptable optimisation toolkit and decision-impact assessment. The exact optimisation method, baseline scenarios, site permissions, consultation plan and validation metrics remain unspecified and should be confirmed before treating any particular technical route as fixed.

School, Programme and Field Context

The official project document places the work in the University of Exeter’s Department of Earth and Environmental Sciences and identifies a PhD in Mining and Minerals Engineering at Camborne School of Mines. The project is based at Penryn in Cornwall. Exeter’s programme page describes research spanning mining and geotechnical engineering, surveying, mineral processing, and mining’s environmental and social impacts. The university reports that Mineral & Mining Engineering was in the QS 2026 subject ranking’s global top 30 and second in the UK; this is a subject-level university signal, not a ranking of this project or its supervisory team. Mining and Minerals Engineering PhD, Earth and Environmental Sciences

The practical environment is relevant to the advertised methods. Exeter lists laser scanners, total stations and high-precision GNSS, and describes computing provision for GIS, mapping, remote sensing, statistics and modelling. Deep Digital Cornwall is described as a CSM/IDSAI-led regional initiative with a 3D modelling and visualisation suite, data hub and links to around 40 small and medium-sized enterprises. These sources establish relevant facilities, but the project-specific equipment allocation, software licences, data storage and external partner commitments are not specified. Department facilities, Deep Digital Cornwall and CSM

Exeter’s Doctoral College offers a staged Researcher Development Programme with online and Cornwall in-person training. The university’s general full-time PhD registration limit is four years; this award funds up to 3.5 years, so applicants should ask what submission milestones and any extension arrangements apply. The degree-awarding institution is Exeter; the DDC and regional organisations are described as research resources or links, not as separate degree providers.

Supervisor and Lab Assessment

Supervisor research directions

The project PDF names Dr Kathryn Moore as lead supervisor, with Prof Matthew Eyre and Dr Iain Soutar as co-supervisors. Exeter’s public materials associate Moore with Camborne School of Mines and research around critical and green-technology metals and multidisciplinary social-earth-science approaches. Eyre is listed in the mining, geotechnical and safety engineering group, whose work includes numerical modelling, mine planning, risk, remote sensing and visualisation. Soutar is a Cornwall-based Senior Lecturer in the Energy Policy Group. Those affiliations suggest complementary mining, modelling and policy expertise, but the sources do not explain the supervisors’ work split or meeting arrangements.

Recent important publications

Three recent Moore co-authored studies offer useful framing rather than a ready-made method for this doctorate:

• Doyle, Moore and Foster’s 2025 criteria-driven socio-environmental maturity model uses maturity assessment and bowtie analysis. It identifies relative strengths in local employment and stakeholder ties alongside gaps in post-closure planning and emergency preparedness. This could inform sustainability or closure-readiness criteria, but it is not a digital-twin validation study. Paper
• Johnson, Moore and Johnson’s 2025 Yukon study combines 20 placer-mine visits with 32 semi-structured interviews to examine livelihoods and human–nature connections. It offers a concrete example of linking field visits to qualitative engagement, while differing in country, mine scale and active-mining context. Paper
• Their 2024 Global North small-scale-mining paper uses archival and ethnographic evidence to assess governance, legal frameworks, economic diversification and rural resilience. It is relevant to the social and institutional dimensions of reuse, but does not model a closed landscape or test optimisation. Paper

Lab, resources, and collaboration environment

The DDC facility and CSM surveying resources align with the stated data collection and modelling work. A key interview question is how those general assets translate into the funded student’s access, training and technical support. Ask whether existing site scans or GIS layers are available, which licences and compute resources are provided, what information partners may share, and what contingency exists if a site or stakeholder becomes unavailable.

Funding, Application, and Living Cost

The Exeter award page identifies this as a 2027/28 EPSRC Doctoral Landscape Award project, reference 6012, with up to 3.5 years of full-time funding. It lists Home tuition, a £5,000 Research Training Support Grant over 3.5 years and says the Home/International fee difference is covered for successful eligible international candidates. However, its detailed funding bullet calls £21,805 the current 2026/27 stipend rate, while the page summary labels the same amount as a 2027/28 rate. Treat £21,805 as the currently displayed amount, not a confirmed 2027/28 guarantee, until Exeter confirms the award letter figure and uprating. General DLA guidance says international awards may make up to 30% of the cohort and that visa fees, the Immigration Health Surcharge and relocation costs are not covered; residency criteria are complex and must be checked. Project-specific award page, EPSRC DLA overview, eligibility and international funding guidance

The application closes at noon on Tuesday 8 December 2026. The project-specific award page says references must arrive by 8 January 2027 and general interviews are likely 15–24 February 2027. General eligibility guidance instead lists references by 15 February and retains 2026 interview/outcome dates despite the 2027/28 intake. To avoid missing a requirement, arrange references for the earlier 8 January date and request written confirmation from admissions. Applications require a personal statement, CV, transcripts, two references and English-language evidence when applicable; documents must be in English. Candidates may submit separate applications for up to three projects and should state their preferred project. Project-specific award page, general eligibility and timeline guidance

The university’s Exeter/Cornwall estimate is £1,300–£2,000 per month for one student, based on local spending guidance. The displayed £21,805 annual amount is about £1,817 per month when divided by twelve, which falls inside that broad estimate; the upper end could leave little room for field travel or other costs. Penryn’s 2026/27 room finder lists self-catered accommodation at £149.66–£199.50 per week and catered rooms at £208.18–£258.02 per week, while warning that 2027/28 prices will change.

Applicant Fit and Preparation

The project description welcomes applicants from different interdisciplinary backgrounds and says applicants are not expected to arrive with every competency. It names geology, mining/civil/environmental engineering, computer science, geography and environmental studies as relevant backgrounds, with interest in surveying and sustainability. The award’s general academic rule is a First or Upper Second UK honours degree or equivalent in an appropriate science or technology area; Lower Second applicants may be considered with a Master’s or significant relevant non-academic experience. Project-specific interdisciplinary flexibility does not remove the award’s academic and residency requirements. Official project description, award eligibility

A focused application can show evidence in one or more of these bridges: GIS or remote-sensing work; field surveying or 3D data capture; geoscience/mining or environmental site knowledge; computational modelling; sustainability assessment; or community consultation. Explain how that experience maps to the six work packages and what skills would need development. A short example of handling uncertain data or making model assumptions transparent would be particularly relevant. The National Careers Service’s environmental-consultant profile describes sustainability, waste, flood risk and climate-impact advice as an adjacent career area, but it is not a forecast of doctoral placements.

Next Actions and Questions to Verify

Before applying

1. Ask Kathryn Moore which South Wales and Portland sites are confirmed, who controls access, and what existing survey, monitoring, infrastructure and environmental datasets are available.
2. Ask admissions to confirm the guaranteed 2027/28 stipend and explain the £21,805 year-label discrepancy in the award page.
3. Ask whether references must arrive by 8 January 2027, as the project-specific page says, or by 15 February, as general guidance says. Plan to the earlier date while waiting.
4. Confirm whether any additional technical submission, GIS/modelling portfolio, research proposal or project-specific English requirement is expected.
5. Build the personal statement around a concrete skill bridge and explicitly state any preferred project if applying to more than one DLA position.

At interview

1. Ask how the project defines the twin, including model boundary, update frequency, data formats, software, uncertainty treatment and validation criteria.
2. Ask which sustainability indicators and optimisation method are anticipated, how local consultation will influence scenario weighting, and how decision impact will be assessed.
3. Ask what access to DDC facilities, computing, technical staff, partners and field-site permissions is guaranteed, including a fallback if an access agreement changes.

Before accepting an offer

1. Obtain written details of stipend amount and uprating, Home and international fee treatment, award start/end dates, the £5,000 RTSG conditions, and costs not covered.
2. Confirm the 3.5-year funded milestone plan, the four-year registration limit, thesis submission expectations and any unfunded extension rules.
3. Ask whether any industry or public-body collaboration is formally committed and whether placements or employment outcomes are evidenced; the public sources do not establish either.

The UK Critical Minerals Strategy links domestic mineral supply, processing and recycling to energy-transition and industrial policy, while the Welsh Government reports continued inspection, monitoring and maintenance of disused tips. The Mining Remediation Authority also reports active mine-water and public-safety programmes. These sources support the broader policy relevance of the topic, not a guaranteed employment route. The Mining Industry Leadership Group’s 2023–2028 sector strategy identifies competence and skills development as concerns, but is industry-authored and does not quantify vacancies.
