Slurry Trenching and Soil Mixing Applications for Tailings Dam Construction and Improvement Coughenour, Nathan; Ruffing, Daniel; Guimont, Hubert

Abstract

Slurry trenching and soil mixing are techniques utilized for a variety of geotechnical and environmental applications and industries. In this paper, the authors discuss slurry trenching and soil mixing applications specifically related to tailings dam construction and improvement including cutoff walls, embankment stabilization, and seismic resilience. Discussions are supported by case study examples of recently completed projects throughout the USA and Canada. Additionally, this paper will provide lessons learned from the authors’ experience with these techniques, including quality control testing, common challenges and methods to overcome those challenges, and recommendations for improvements to specifications and design of these techniques.
