Abstract The transition from mineral extraction to post-mining land use is conventionally structured as a sequential process where recreational functions are introduced after extraction ceases. This temporal separation limits opportunities to incorporate long-term land-use objectives into active mine design and leaves unresolved questions regarding how industrial, ecological, and institutional functions can be coordinated across the mine life cycle. This conceptual paper develops the Integrated Interface Model (IIM), a framework for examining how mineral extraction and progressive landform transformation can be analyzed as interacting components of mine-transition planning. The framework synthesizes Social-Ecological Systems theory with the Industrial Sublime as complementary analytical perspectives, utilizing the Hyper-object concept to address the spatial scale and temporal complexity of surface mining landscapes. A conceptual theory-building methodology was conducted to identify structural relationships among mine-system processes, landform geometry, governance, and post-mining land transition. The Eden Project and Lusatian Lake District are examined as illustrative post-mining precedents that inform the model but do not constitute empirical validation of active extraction concurrent with public access. The resulting IIM organizes the interface across three dimensions: Spatial, concerning sectoral zoning (Z1-Z3) and geotechnical safety setbacks; Temporal, concerning deep-time hydrological phasing; and Institutional, concerning financial assurance through the Recreational End-Use Bond. Derived theoretical propositions concerning regulatory friction (P1), post-closure asset valuation (P2), and institutional trust (P3) are framed as hypotheses requiring future empirical, geotechnical, regulatory, and economic testing rather than established operational effects.
