Tailings Dam Design

Greens Creek Mine, Alaska Engineering and consulting services are offered for the investigation, design, operations optimization, remediation and closure of tailings dams. Experience has been gained on the design and construction of all types of tailings impoundments including the constructed of tailings, earth, mine rock and concrete by downstream, center line and upstream methods. Facilities have been designed for the handling, transportation and placement of dry (dewatered) tailings, cycloned tailings and slurries by a variety of spigotted (subaerial and sub aqueous) systems.

Typical projects include

  • site selection and alternative site studies for the optimization of tailings impoundment site selection
  • site investigation and material laboratory testing for foundations and the identification of construction materials and placement requirements
  • investigations and instrumentation of existing tailings dams for stability assessments or expansion design
  • testing of tailings materials and studies on placement characteristics and opportunities for waste characteristics improvement
  • design and construction supervision of a wide variety of tailings impoundments
  • optimization studies and re-development designs of tailings dams to improve stability, water return, reclamation, increase capacity, reduce contaminated seepage or reduce operating costs
