DURATION: TERM 1 2 3
DURATION: WEEKS 11
Number of Students Taking Module (anticipated) 20
DESCRIPTION - summary of the module content

Module content covers subjective & theoretical elements (ventilation words & concepts, underground hazards & ventilation economics) and mathematical elements (airflow, ventilation thermodynamics & psychometry. This is an essential topic for all mining engineers and is the real life application of engineering science subjects such as fluid mechanics studied in years one and two.

AIMS - intentions of the module

The module extends understanding of engineering principles in relation to the environmental conditions that are encountered in the workplace and the application of these principles to the ventilation of underground excavations and surface facilities.

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 recall or recognise most of the facts, concepts and techniques of the syllabus plan;

2 analyse data within contexts covered in the syllabus with some guidance, using the majority of techniques covered in the syllabus plan;

3 transform data and concepts towards a clearly specified purpose and produce designs to problems within contexts explained within the syllabus plan;

4 conduct observations of the condition of the working environment or a ventilation system with minimal guidance;

5 understand the factors that influence the condition of the working environment or the operation of ventilation systems;

6 recognise that there are inconsistencies or errors in data and methods;

7 identify solutions to complex problems that are similar to those covered in the syllabus plan.

Discipline Specific Skills and Knowledge

8 make use of the majority of resources that support the syllabus plan;

9 choose a design method from the syllabus plan;

10 conduct calculations correctly, neatly and be able to comment whether the answers make sense.

Personal and Key Transferable / Employment Skills and Knowledge

11 use independent learning skills for the solution of worksheet problems;

12 demonstrate group working skills;

13 show data-handling skills through critically evaluation of a design problem and produce, to a strict deadline, detailed recommendations/reasoned arguments for an appropriate solution;

14 illustrate report-writing skills;

15 display IT skills and become familiar with specialist mine ventilation software.
