Improving Slope Stability Analysis: The Role of Calibrated 3D Numerical Models
Wednesday, April 17, 2024, 08:30 AM - 09:00 AM
This article aims to present the developed calculation used for conducting calibration models. It relies on the implementation of local 3D models, which have served as a foundation for comprehending the diverse range of parameters and their influence through back analysis development for a failure that occurred in past.

Reducing Design Uncertainty by Better Handover to Mine Planning
Wednesday, April 17, 2024, 10:30 AM - 11:00 AM BRT
Case studies of three deposits were assessed using a simplified approach to pit optimization at a theoretical PEA level. These are not intended to showcase a specific workflow that must be followed, but rather to show examples of how the geotechnical risk can be considered when developing the slope design.

Hard Rock Groundwater Depressurization Responses and the Observations That Support Calibrated Pore Pressure Model at Rainy River Mine, Ontario, Canada
April 14 - 19, 2024, 01:00 PM - 01:30 PM BRT
This study investigates the relationship between rock mass, anisotropy, excavation, and blasting influences on the observed groundwater depressurization trends at New Gold's Rainy River Mine located in Ontario, Canada using vibrating wire piezometers (VWPs) installed around the perimeter of the open pit. The study findings are used to verify design stability conditions, and when needed, calibrate pore pressure models.

Equivalent Geological Strength Index Approach with Application to Rock Mass Slope Stability
Thursday, April 18, 2024, 09:00 AM - 09:30 AM
A considerable amount of slope stability analysis has been observed in jointed rock masses in which the Geological Strength Index (GSI) estimated at the outcropping level is considered input data to define the rock mass strength. However, this procedure is unsuitable when the rock outcrop and the slope scales are significantly different (e.g., open-pit slopes), resulting in an overestimated rock mass strength.
