Course Summary

Introduction

Guidelines for Open Pit Slope Design 2 - Modelling is the second in a series of four courses on open pit slope design. The complete Guidelines for Open Pit Slope Design series includes:

  • Fundamentals and Data Collection
  • Modelling
  • Design
  • Operation
The design of the slopes is one of the major challenges at every stage of planning and operation of an open pit mine. It requires specialised knowledge of the geology, which is often complex in the vicinity of orebodies where structure and/or alteration may be key factors, and of the material properties, which are frequently highly variable. It also requires an understanding of the practical aspects of design implementation.

Part 1 of this course discusses the geological model and its purpose of linking the regional physical geology and the events that lead to the formation of the ore body to a mine-scale description of the setting; distribution; and nature of the overburden soils and rock types at the site, including the effects of alteration and weathering.

Part 2 discusses the structural model and its purpose of describing the orientation and spatial distribution of the structural defects that are likely to influence the stability of the pit slopes.

Parts 3 and 4 discuss the rock mass model and its purpose of representing the engineering properties of the rock mass for use in the stability analyses that will be used to prepare the slope designs at each stage of project development.

Parts 5 and 6 discuss the hydrogeological model and how the presence of groundwater and the resulting pore pressures may affect open pit slope design and performance.

Part 7 outlines the iterative processes used to bring the model components into the geotechnical model so that geotechnical domains and design sectors can be fixed and employed in the slope design process.

Content

The course comprises 23 learning sessions of between 60 and 90 minutes each at the text level, plus multiple-choice reviews, extensive worked examples, numerous illustrations and tables, and supporting appendices. Estimated course duration is equivalent to approximately 34 hours of viewing content.

Learning Outcomes

  • Discuss the development and objectives of the geological, structural, rock mass and hydrogeology models required to compile a geotechnical model for the slope design process.
  • Identify and apply the processes used to bring the model components into the geotechnical model so that geotechnical domains and design sectors can be fixed and employed in the slope design process

Recommended Background

  • A degree in mining or geotechnical engineering, engineering geology or related discipline.
  • A basic grounding in rock mechanics and experience in open pit operations.
