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 1 & 2.

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)

Module Specific Skills and Knowledge: (Threshold Attainment):

1.Candidates should be able to recall or recognise most of the facts, concepts and techniques of the syllabus plan

2.Candidates can often analyse data within contexts covered in the syllabus with some guidance, using the majority of techniques covered in the syllabus plan.

3.With guidance the candidate can transform data and concepts towards a clearly specified purpose and can produce designs to problems within contexts explained within the syllabus plan.

4.Candidates can conduct observations of the condition of the working environment or a ventilation system with minimal guidance.

5.Candidates should be able to understand the factors that influence the condition of the working environment or the operation of ventilation systems.

6.Candidates can recognise that there are inconsistencies or errors in data and methods.

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

Discipline Specific Skills and Knowledge: (Threshold Attainment):

1.Candidates will have made use of the majority of resources that support the syllabus plan.

2.Candidates can often choose a design method from the syllabus plan.

3.Candidates will conduct calculations correctly, neatly and be able to comment whether their answers make sense.

Personal and Key Transferable/ Employment Skills and  Knowledge:

1.Independent learning skills are used for solution of worksheet problems.

2.Group working skills are developed through implementation of the experiments conducted at King Edward Mine.

3.The student should be able to develop data-handling skills through critically evaluation of a design problem and produce, to a strict deadline, detailed recommendations/reasoned arguments for an appropriate solution.

4.The student will develop report-writing skills.

5.The student will also develop IT skills and become familiar with specialist mine ventilation software.
