DESCRIPTION - summary of the module content

The module provides knowledge relating to the design of surface excavations. This includes both geotechnical design-related aspects and blast-design of surface excavations. Pre-requisites are to have studied CSMM100 or CSMM103. The module is not recommend for the interdisciplinary pathway.

AIMS - intentions of the module

The module provides specialist analysis and design skills associated with civil, geotechnical, environmental and related industries. The module provides problem-solving skills and provides simulated industrial experience.

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

Module Specific Skills and Knowledge:

1

Assess critically the role and limitations of analytical and computer methods in surface excavation stability analysis and design.

2

Evaluate factors controlling instability and reinforcement design of slopes

3

Determine the data requirements for the design of surface excavations, including considerations of data variability and risk assessment.

4

Understand and evaluate critically the key components for the design of blasting for surface excavations.

Discipline Specific Skills and Knowledge:

5

Evaluate and apply knowledge to specific design tasks.

6

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

7

Undertake synthesis of information and create responses based on advanced knowledge.

Personal and Key Transferable/ Employment Skills and  Knowledge:

8

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

9

Utilize a range of computer-based learning resources as an autonomous learner.
