(WSP) is pleased to host this workshop in association with the Slope Stability 2024 Conference on the topic of Discrete Fracture Network (DFN) Analysis for Open Pit Slope Stability. Over the last decade, DFN analysis and modelling have resulted in significant advances in how we approach fractured rock masses. A major area of development has been in DFN-based slope engineering, with advances in bench-scale analysis as well as inter-ramp and wall-scale stability analysis. This short course introduces attendees to some of the theory behind DFN modelling and some practical examples of how it is used, while providing hands-on experience with WSP’s DFN software, FracMan®. All attendees will be provided with a 30-day licence for the geotechnical edition of FracMan® Participants should bring a laptop to this workshop. This workshop will cover the following key topics: § How to describe a rock mass using DFN methods and how to define the key probabilistic input parameters. § The advantages of DFN-based bench-scale analysis over conventional bench-scale kinematics. § Using DFN methods to evaluate rock mass fragmentation and block size distributions. § How to evaluate rock-bridge percentage and mixed (joint-rock mass) shear strengths for input into two‑dimensional (2D) stability assessments. § How to run slope-scale kinematic assessments on intermediate and major structures using geologically constrained DFN models. § How to incorporate rock mass strength and pore pressure into slope-scale assessments.	09:00 - 12:00 WORKSHOP 1 - WEAK ROCK SAMPLING AND LABORATORY TESTING FOR OPEN PIT OPERATIONS (WSP/LOP) LUIZ CASTRO WORKSHOP SPEAKER MARC ROUGIER WORKSHOP SPEAKER MARISOL VALERIO WORKSHOP SPEAKER SHARON ROSS WORKSHOP SPEAKER This workshop for pit slope stability practitioners, developed in collaboration with the Large Open Pit project, provides guidelines for rock sampling and laboratory testing in weak rock for open pit slope design applications. The workshop aims to introduce attendees to the challenges unique to weak rock and different from hard rock, and provide insights on how to handle these challenges when sampling, field testing, and planning laboratory strength testing with weak rock.

In the majority of cases, slope monitoring programs are able to manage geotechnical risk in the short term, namely detecting slope movements a few days or hours before the collapse and communicating with operations in order to remove personnel and equipment from the potential run-out area. Additional efforts are still necessary to support better exploitation of the available data aimed at the identification of anomalous behaviors of the monitored slopes. The available data, if properly analyzed and interpreted, may contain valuable information potentially able to identify unstable sectors of the slope weeks or months before movements are fast enough to be detected by radar. The workshop is aimed at describing this type of process, namely 'data analytics'.	13:30 - 17:00 WORKSHOP 8 (PART 2) - DISCRETE FRACTURE NETWORK (DFN) ANALYSIS FOR OPEN PIT SLOPE STABILITY PEDRO OJEDA WORKSHOP SPEAKER SANTIAGO MARAMBIO WORKSHOP SPEAKER WSP Canada Inc.

DEMONSTRATION THROUGH CASE STUDIES OF FOUR OPEN PIT MINES STEFANO UTILI WORKSHOP SPEAKER MATTHEW SCHMIDT WORKSHOP SPEAKER SERGIO CUELLO WORKSHOP SPEAKER In the current design practice, pit wall profiles are often designed to be planar especially within each rock layer. A new slope design software, OptimalSlope, has been recently introduced to determine non-planar geotechnically optimal pitwall profiles. These profiles are obtained as the solution of a mathematical optimisation problem where the overall slope angle of the pitwall, from crest to toe, is maximised for an assigned lithology, rock properties, FoS, and any ramp to be accommodated. Participant will be introduced to the theory behind OptimalSlope and 4 case studies of open pit mines where the adoption of overall steeper optimal pitwalls and their integration with strategic mine planning software has led to a significant reduction in the amount of waste rock to be excavated (up to 27% of total waste rock volume) and in turn in higher profits for tens of million USD (from 11 to 140 million) and carbon footprint reductions of 600,000 tonnes CO2eq on average per mine (see: https://optimalslope.com/Case-Studies.html). Participants with a computer will also be given the opportunity to use OptimalSlope graphical user interface and its slope optimiser.
