ENAR12006 - Rock Engineering
Term 2 - 2017


All details in this unit profile for ENAR12006 have been officially approved by CQUniversity and represent a learning partnership between the University and you (our student). The information will not be changed unless absolutely necessary and any change will be clearly indicated by an approved correction included in the profile.

Overview

You will be introduced to critical concepts in the application of geo-technical methods to mining operations. The methods and procedures you will learn will cover rock testing, design of underground openings, and pillar and ground support design. You will gain an understanding of how underground mining methods can impact on infrastructure and aquifers through subsidence. You will also learn how to analyse the stability of slopes generated by open pit mining operations. Throughout the unit you will be required to demonstrate professional levels of teamwork and communication. You will attend a Residential School where you will engage in activities designed to assist you to achieve the Learning Outcomes for the unit.

This is a graded unit: your overall grade will be calculated from the marks or grades for each assessment task, based on the relative weightings shown in the table above. You must obtain an overall mark for the unit of at least 50%, or an overall grade of ‘pass’ in order to pass the unit. If any ‘pass/fail’ tasks are shown in the table above they must also be completed successfully (‘pass’ grade). You must also meet any minimum mark requirements specified for a particular assessment task, as detailed in the ‘assessment task’ section (note that in some instances, the minimum mark for a task may be greater than 50%). Consult the University’s Grades and Results Procedures for more details of interim results and final grades.

4 Practical Assessment

Assessment Title Practical Assessment - Mining Lab, Mackay Ooralea Campus
Task Description

The practical assessment will consist of four components to be completed as part of a team.

Part 1. If available, a one day visit to a mine site in the Mackay region will be arranged. Ground support and rock mechanics issues pertinent to that mine site will be reviewed. Students will be required to identify major risks associated with ground conditions at that mine. They will also be required to identify the controls the mine has in place to mitigate those risks. When the mine site visit has been confirmed a worksheet will be forwarded to the students instructing them on suitable preparation for part 1 of the practical.

Part 2 will require students to complete a laboratory session using a point load rock testing machine.

Part 3 will require students to present their findings from their mine site visit and lab session.

Part 4 will require students to write up and submit a team report of the details of the mine site visit and the lab report on the last day of the residential school.

The residential school will be based in Mackay during the break week of term 2, 2016.

Assessment Due Date Final day of residential school.
Return Date to Students Within 2 weeks of the assessment submission.
Weighting Pass/Fail
Assessment Criteria

Students will be assessed on their ability to,

  • work as part of a team
  • comply with instructions from mine site personnel
  • demonstrate an understanding of the rock mechanics issues at the mine.
  • participate in discussions and lab work
  • present their findings
  • contribute to a team report

Feedback sheets will be provided to cover each of these activities.Successfully completing 75% of the exercises detailed in the Residentail School will achieve a Pass for this assessment.
