Geosynthetic liners for sustainable development of Arctic mineral resources

2019/20 • $198,254
Extraction of mineral resources contributed $56 billion to Canada's economy in 2015. More than $8 billion in new mineral resource development is anticipated in the next decade alone in the Canadian Arctic. These activities involve generation of contaminated water that needs to be managed in a...

Self-centering rocking steel bridge piers for seismic regions

2018/19-2019/20 • $112,000
The proposed research will introduce prefabricated post-tensioned steel bridge pier that will not only enable structures to be built faster but also help structures self-center after major earthquakes. Performance-based design is becoming a standard practice for seismic design and evaluation of...

CanBreach (Canadian Tailings Dam Breach Research) - an integrated tailings dam breach research and technology development project

2019/20 • $80,000
Mining produces massive volumes of waste, called tailings, which are stored forever behind large dams. If a tailings dam breaks, as one did recently at the Mount Polley mine near Williams Lake, British Columbia, the tailings can flow long distances, and major safety, environmental and economic...

Implementation of New Monitoring Approaches for Geohazard-Risk Management in Canada

2019/20 • $43,000
Transportation infrastructure, including roads, pipelines, transmission lines and railways, provide necessary interconnectivity within the country, and their adequate performance is a matter of continuous monitoring and maintenance. Transportation infrastructure is exposed to geohazards...

Assessment of Residual Strength of Tailings Using the Cone Penetration Test and Simplified Numerical Modelling

2019/20 • $33,286
Tailings dams are massive man-made earth structures used for disposing large quantities of mining by-products, known as tailings. A great majority of the rock crushed for ore extraction does not contain sufficient amounts of desired minerals. These silt-and-sand-sized materials are mixed with...

Chaire de recherche industrielle CRSNG/Hydro-Québec sur l'optimisation du cycle de vie des barrages en remblai

2014/15-2018/19 • $1,049,998
L'approche d'optimisation du cycle de vie consiste à évaluer l'état d'un ouvrage et à prédire son évolution dans le temps afin de fournir au propriétaire averti une démarche globale de saine gestion permettant de maximiser la durée de vie des ouvrages tout en minimisant les coûts d'entretien et...

Geosynthetic liners for sustainable development of Arctic mineral resources**

2018/19 • $196,714
Extraction of mineral resources contributed $56 billion to Canada's economy in 2015. More than $8 billion in new mineral resource development is anticipated in the next decade alone in the Canadian Arctic. These activities involve generation of contaminated water that needs to be managed in a...

Tailing migration though geomembrane holes

2016/17-2017/18 • $39,490
Management of mine tailings (waste generated after resource extraction) in both a safe and environmentally acceptable manner is essential for continued activity in this important sector of Canada's economy-worth $57B in 2014. Increasingly, the long-term discharge of contaminants from the...

Effect of pile shape on effectiveness of ground improvement by compaction piling

2017/18 • $24,500
Ground improvement by compaction pilling is widely used to increase the resistance of loose sands toliquefaction. Better understanding of seismic risk and the increasingly severe design criteria in modern designcodes have led to a need for technically and cost efficient approaches to remediation...

Implementation of new monitoring approaches for geohazard-risk management in Canada

2017/18 • $23,500
Transportation infrastructure, including roads, pipelines, transmission lines and railways, provide necessaryinterconnectivity within the country, and their adequate performance is a matter of continuous monitoring andmaintenance. Transportation infrastructure is exposed to geohazards associated...

Soil-specific cone penetration test interpretation framework for tailings

2016/17 • $25,000
Tailings dams are massive man-made earth structures used for disposing large quantities of mining byproducts, known as tailings.A great majority of the rock crushed for ore extraction do not contain sufficient amounts of desired minerals. These silt-and-sandsizedmaterials are mixed with water...

Leakage through a hole in a geomembrane liner for tailings dams

2012/13-2013/14 • $53,539
At 36 billion dollars in 2010, Canada's mining industry directly accounted for 3.5% of our economy (Stats Can). The solid waste by-products generated by mineral extraction need to be managed in a sustainable manner to maintain and grow this significant economic activity. Most of these wastes are...
