Surface Mining and Mine Transport - 2021 entry

In this module, you will learn about the surface mining industry, and examine both the machinery that practitioners use, along with its associated methodologies, which you will critically examine and discuss. The Mine Transport section of the module focuses predominately on the four principle methods of underground mine transport and relies heavily on numerical examples to show how the transport methods are both selected and optimised.

Pre-Requisite module: CSM1029; or equivalent.

This module is unsuitable for non-specialist students.

This module is not recommended for interdisciplinary pathways.

The principle aim of this module is to develop your understanding of the techniques of surface mining and equipment used. Additionally this module examines the methods of mine transport that practitioners may well use in an underground operation. It also aims to extend your understanding of engineering principles in relation to the handling and transport of men and materials.

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