Inco Tailings Pond, Sudbury, Ontario, Canada
The above photo shows the ground reaction immediately following blast densification at a tailings pond in Sudbury, Ontario. Blast densification induced soil liquefaction, and excess pore-pressure was relieved through pre-installed vertical wick drains. This allowed rapid consolidation of the tailings pile, subsidence of the ground surface.
Rapid Impact Compaction and traditional Dynamic Compaction were also used as ground improvement measures for this project.
