  • Learning Outcomes
    Course Learning Outcomes
    The purpose of the course is to introduce the students to methods of testing, analysis and design appropriate to rock masses. It is anticipated that on completion of the course the students will:
    1. Have a working knowledge of the engineering properties of rock
    2. Be able to select and use appropriate analytical and numerical methods for the design of underground structures and support systems
    3. Have the necessary grounding in rock mechanics to embark upon a study of the principles of rock engineering
    4. Recognise the evolving nature of the discipline and develop skills to access, evaluate and integrate new knowledge and processes.
    5. Explain the contribution of rock breakage to the mining process
    6. Describe the various methods of rock breakage
    7. Select appropriate methods of drilling and rock breakage for given in-situ rock conditions
    8. Apply fundamental principles to the design and selection of safe and efficient blasting to:
    a. Design blasts to achieve particular outcomes
    b. Manage and control blast damage and environmental impacts
    c. Evaluate productivity and economics

    The Course will contribute to the development of the following attributes:
    1. Appropriate technical knowledge
    2. Skills of analysis, synthesis and problem solution, and the ability to tolerate ambiguity
    3. Lifelong ability to learn

    Specific Course Requirements
    Laboratory exercises

    Please refer to the Rock Mechanics Laboratory Handout and also the Video Introduction to the Rock Mechanics Laboratory Exercises uploaded onto Canvas. It will be assumed that you have studied the handout and the video introduction prior to your arrival in the laboratory, so you will be given minimal instruction. Academic and technical staff will be on hand to assist and to answer any questions.

    The eight exercises in this program have been designed to provide an introduction to, and awareness of, basic measurements and test procedures in rock mechanics. The tests will be conducted in the Engineering Annex (LG09), Room NG31 and adjacent areas. Mechanical tests will be conducted on 42 mm diameter Hawkesbury Sandstone specimens.

    The class has been randomly divided into Groups of 3-5 students. Each Group will work separately through the eight exercises. Each Group will test only one specimen in each of the destructive tests (1, 2, 4a and 4b) then share their results with the class after two weeks of completion of the tests. Please use the template table provided on Canvas. If one of your destructive tests is unsuccessful, describe what happened in your report, then use the results obtained by another Group. Each Group will attend the laboratory on two occasions: Once to undertake tests 1, 2 and 3 and once to undertake tests 4, 5, 6 and 7.

    Your Group has limited time to conduct these tests so it is imperative that you are well prepared and arrive on time. You will not have time to read through the laboratory handout during the laboratory session, so it is important you study this handout and also the video introduction prior to your session. When you arrive in the laboratory, sign in, locate your test equipment and specimens then start preliminary measurements immediately. Technical staff will be on hand to show you how to operate the mechanical test equipment. Sign out as you leave the laboratory. If you do not sign in and sign out we will assume you have not attended the session. If you are unable to attend your scheduled laboratory session due to illness or other unavoidable factors and are able to submit a doctor’s certificate, join another group and undertake the exercises at another time. Alternatively, make arrangements with the lecturer to attend during one of the spare sessions.
    This laboratory program carries a weighting of 15% for the course. Group reports must be submitted through CANVAS by the deadline to be set by the course coordinator. These laboratory exercises are a compulsory component of the course. Students who do not attend the laboratory sessions and/or do not hand in a laboratory report will fail the course. Students who do not attend the laboratory sessions (or do not sign in and out), but do hand in a laboratory report based on results obtained by other students, will fail the course.
  • Assessment

    The University's policy on Assessment for Coursework Programs is based on the following four principles:

    1. Assessment must encourage and reinforce learning.
    2. Assessment must enable robust and fair judgements about student performance.
    3. Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
    4. Assessment must maintain academic standards.

    Assessment Summary

    No information currently available.

    Assessment Related Requirements
    In order to pass the course, students are required to attend the final exam and receive a minimum of 40% of the total mark from the final exam. Students who get marks less than 40% from the final exam will fail the course.
    The laboratory exercises are a compulsory component of the course. Students who do not attend the laboratory sessions and/or do not hand in a laboratory report will fail the course.

  • Student Feedback

    The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.

    SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

  • Student Support
  • Policies & Guidelines
  • Fraud Awareness

    Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.

The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
