An operational approach to geomorphic design in mine reclamation : A case study from Teck Coal Line Creek Operations Dube, J.; Formanski, D.

Abstract

In 2023, Teck Coal Limited embarked on a three-year phased project for geomorphic landform design at an existing mine rock spoil within Line Creek Operations. Landform design has many components; however, this scope will focus on the engineering perspective of the bulk re-slope of West Line Creek Spoil. Material movement inherently has constraints related to material type, equipment selection, geotechnical considerations, and economics. The process of creating a geomorphic design for West Line Creek Spoil was primarily a desktop exercise, that was iteratively improved through reviews of field experts, and is being implemented in the 2024 construction season. The West Line Creek geomorphic design process results in an increased variability in slopes and aspects which has a positive contribution to biodiversity objectives while maximizing operational safety, mine production and managing geotechnical constraints. This paper discusses the design approach at Line Creek Operations and outlines the benefits and practical learnings for reclaiming a mine rock spoil by integrating geomorphic features. It aims to demonstrate the effectiveness and learnings of a thorough design approach in achieving sustainable closure goals.
