<p>A study of three translational landslides along the North Saskatchewan River Valley in Edmonton is presented in this paper. The major focus is on kinematics and mechanisms of deep seated landslides in bedrock of the Upper Cretaceous Horseshoe Canyon Formation. ...

Deep seated retrogressive earth slides along the walls of the Little Smoky River valley, in northwestern Alberta, have lead to significant ongoing maintenance on Highway 49 for the past 50 years. While localized, higher velocity zones, have lead to site specific ...

Canadian railways are exposed to various ground hazards because of the diverse geographic regions of the country. Keegan (2007) analysed these hazards and proposed hazard scenarios to evaluate the influence of these hazards on railway operations. Process modelling ...

<p>Observations of pillar failures in Canadian hard-rock mines indicate that the dominant mode of failure is progressive slabbing and spalling. Empirical formulas developed for the stability of hard-rock pillars suggest that the pillar strength is directly ...

A review of underground openings, excavated in varying rock mass types and conditions, indicates that the initiation of brittle failure occurs when the damage index, Di , expressed as the ratio of the maximum tangential boundary stress to the laboratory unconfined ...

Stope design in Canadian hard rock mines is often carried out using the Stability Graph Method. However, this method does not account for the low confinement measured around stopes or quantify the amount of dilution associated with stope caving. A new approach ...

Stress-strain curves for brittle rocks show three characteristic stress levels: crack initiation, long-term strength, and peak strength. Damage-controlled testing at low confining stresses has shown that the long-term and peak strengths are sensitive to the ...
