DESCRIPTION - summary of the module content

This module provides application of rock engineering principles to the design of underground excavations. It uses analytical, empirical and observational design approaches to assess excavation dimensions and understand the detrimental effect of stress redistribution around underground excavations. Studnets are also given an awareness of factors influencing the choice of appropriate tunneling machines for different underground environments. The material is taught through a series of lectures and case examples. Students are required to submit an assessment based on a design exercise.

Students should have studied CSM2300 or equivalent.

This module is unsuitable for  non-specialist students

This module is not recommended for interdisciplinary pathways.

AIMS - intentions of the module

The module provides specialist analysis and design skills associated with the tunneling, underground mining and related industries. The module provides problem-solving, data-handling and evaluation skills.

INTENDED LEARNING OUTCOMES (ILOs) (see assessment section below for how ILOs will be assessed)

On successful completion of this module you should be able to:

Module Specific Skills and Knowledge:

1.Understand the use of rock engineering for the design underground excavations in the mining, civil, geotechnical, environmental and related industries.

2.Understand the role and limitations of analytical and computer methods in underground excavation design

3.Understand the data requirements for the design of underground excavations, including considerations of data variability and risk assessment. 

4.Be able to analyse and determine appropriate design of underground excavations in varying rock material.

5.Understand the use of analytical, empirical and observational design methodologies in specialist geotechnical applications.

6.Choose an appropriate tunneling technique for varying rock and soil material.

Discipline Specific Skills and Knowledge:

7.Evaluate and apply knowledge to specific design tasks.

8.Create an appropriate design from the evaluation of available data.

9.Undertake synthesis of information and create responses based on current knowledge.

Personal and Key Transferable/ Employment Skills and  Knowledge:

10.Develop personal data-handling skills through critically evaluation of a design problem and produce, to a strict deadline, a report with detailed recommendations / reasoned arguments for an appropriate solution.

11.Utilize computer-based learning resources as an autonomous learner.
