DESCRIPTION - summary of the module content

This module looks at “risk” in its most common applications within industry today, which is related to (i) projects and engineering design and (ii) health and safety management. Content is highly vocational and the skills and knowledge gained will be beneficial and used by students whilst in employment, particularly in the extractives industry.

AIMS - intentions of the module

The module provides an introduction to hazard and risk assessment methods and legislation and provides theoretical and practical case examples applicable to typical projects in mining and civil engineering.

It is intended that the students learn from a combination of traditional lectures, assignments and site visits, supported by the use of ELE and other electronic methods

Written

The two summative assignments are used to develop understanding of key aspects. Each is based on actual project data or data obtained by the students themselves. Assignments are selected from the following typical examples and address the numbered intended learning outcomes indicated:

  • Hazard appraisal and risk assessment at a local quarry, as required by the Quarries Regulations (1999): 2,3,4,5,6,8 ;
  • Qualitative risk assessment and mitigation of potentially hazardous working conditions in underground mining: 2,3,4,5,6,8 ;
  •  Risk assessment and risk based design for potentially unstable rock slopes adjacent to active roads: 1,2,5,6,7,8, 9 ;
  • Risk assessment and mitigation in use of toxic chemicals in mineral processing: 1,2,3,5,6,7,9 ;
  • Risk assessment of stability of water and tailings dams: 1,2,3,5,6,7,8,9
  • Risk assessment of transport operations in quarrying or underground mining: 2,3,4,5,6,7,8,9.

The assignments typically take the form of a technical reports of maximum 1500 words, together with appropriate use of graphs, calculations, references. Emphasis is on interpretation, recommendations and where appropriate, worked solutions.

In addition, formative assignments are embedded in lectures / seminars. Typically these might include :

  • development of a hazard influence diagram and associated fault tree for a subject of student choice: 1,7,8;
  • team effort using the Delphi system for risk assessment avoiding subjective bias: 1,7,8.
  •  team analysis and presentation of hazards determined from a local quarry visit: 2,3,4,5,8,9.
