Abstract:
The geomorphic landform design (GLD) investigated in this paper is part of the ongoing development of the future waste management strategy for the Svappavaara mine site. This strategy considers various expansion options for the two existing open pits, Leveäniemi and Gruvberget, including large, medium and small pushbacks, as well as extending the pits underground. The expansions are expected to generate significant quantities of both waste rock and dry waste. Consequently, the future waste management strategy proposes a conventional terraced waste rock dump design, which maximises opportunities for future mining scenarios. However, the proposed conventional terraced waste rock dump design involves substantial material movements and results in environmental degradation, loss of biodiversity and sterile post-mining landscapes – factors that negatively impact the social licence to mine. An alternative GLD could support medium- to large-sized expansions; meeting volume criterion, facilitating ongoing restoration and reducing the negative visual impacts of the industrial area. These factors align with LKAB’s sustainability policy, contributing to a sustainable mining industry, increased biodiversity and efficient use of natural resources. The primary aim of this paper is to present a conceptual GLD as a part of future waste management strategy for LKAB. Additionally, the GLD workflow is detailed, including relevant landscape inputs, design criteria, runoff and slope zone analysis to ensure proper landscape function. Finally, an optimised lift plan is created for the GLD, enabling the use of standard site equipment and minimising material movement.
