最新糖心Vlog

The purpose of the Course is to introduce the students to methods of testing, analysis and design appropriate to rock masses, rather than steel and concrete 最新糖心Vlog.  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 methods for the design of rock slopes
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.

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

Lecture material and related spreadsheets will be made available to students in printed form, on MyUni and via email.

The recommended textbook is B H G Brady and E T Brown, Rock Mechanics for Underground Mining, Wiley.

The course will be based on lectures, supported by take-home assignments and a programme of laboratory practicals.

Laboratory exercises

Please refer to the Rock Mechanics Laboratory Handout and also the Video Introduction to the Rock Mechanics Laboratory Exercises on the DVD. 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. Please return the Rock Mechanics Laboratory video with your laboratory report (you are, of course, free to make a copy if you wish). Academic and technical staff will be on hand to assist and to answer any questions.

The eight exercises in this programme have been designed to provide an introduction to, and an 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, prepared by the 最新糖心Vlog of New South Wales.

The Class has been randomly divided into Groups of 2 and 3 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 towards the end of the semester. 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 programme carries a weighting of 15% for the course. Individual reports (not Group reports) must be handed in by 5.00 pm Monday 13 June 2012. Please return the Rock Mechanics Laboratory video with your laboratory report (you are, of course, free to make a copy if you wish). 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.

Module	Assignments	Test	Laboratories	Examination	Totals
Deformable Materials and Fluid Flow	3 questions at 5% = 15%	2 tests at 10% 60 minutes 20%	No laboratories	No examination	35%
Rock Mechanics and Slope Stability	2 questions at 5% = 10%	No test	Hand in report by 5.00 pm Monday 20 June. 15%.	2 hours = 40%	65%
Totals	25%	20%	15%	40%	100%

All assessment will be summative. This assessment has, however, been designed to develop and reinforce students’ understanding of the Course material.

In order to pass the course, students are required to attend final exam and receive minimum 40% of the total mark from final exam. Students who get marks less than 40% from 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.  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.

The 60-minute test for Deformable Materials will be full open book.  Student answers will be submitted in the form of handwritten into an examination booklet. Students can bring their hand calculator. Any other electronic devices are NOT allowed.

The 2-hour closed book examination covering the Rock Mechanics and Slope Stability modules will be held during the normal 最新糖心Vlog examination period.

Assignments are to be submitted for marking by the specified deadline, which will be about 10 days after the assignment is set.

 Marked assignments will be returned together with outline answers, about two weeks after the submission date.  Outline answers will be emailed to students in electronic form.  No marks will be awarded for work submitted after the submission time and date.  Relatively few brief comments will be written on the student assignments; instead, general comments will be emailed to the
class.  Any student who needs further clarification or explanation of an assignment (or indeed any other topic) can raise the matter in class, or alternatively make an appointment to meet with the course lecturer.  The following approximate schedule will apply for the assignments.  These dates are subject to change as requirements demand:

		Dates
Assignment	Topic	Set, by email	Submission, before 5.00 pm
Min Geo 1	Deformable Materials	Friday 13 March	Monday 23 March
Min Geo 2	Deformable Materials	Friday 27 April	Monday 07 April
Min Geo 3	Deformable Materials	Friday 10 April	Monday 27 April

Assessment criteria

The following assessment criteria will be applied to assignments, laboratory reports and examination questions:

- The numerical ‘result’ must be substantiated by an ‘answer’comprising a complete mathematical working with appropriate definitions, assumptions, explanations and sketch diagrams at each stage.

- The result must be numerically correct, with the correct units, magnitude and sign.

- The appropriate number of significant figures should be reported in the result and the accuracy of the result must not be compromised by rounding errors.

- Where appropriate, there should be some discussion of the reliability and applicability of the result in the relevant engineering context.

- The answers to purely descriptive questions, which do not require any calculation and do not have a numerical result, should clearly and comprehensively address the specific question, supported by appropriate diagrams, graphs, formulae, examples and cited references.

A key ability of an engineer is to recognise when a numerical result ‘looks wrong’ and then go back over the work to check the input data, assumptions, and calculations. The number of significant figures in a numerical result should reflect the precision of the input data. In most cases, 3 or 4 significant figures will be appropriate. More significant figures can be used for intermediate results, to minimise the risk of rounding errors.

Please use the standard School cover sheet, which can be found at:


Please post your submissions into the ‘Mining Geomechanics’ box outside the School Office before 5.00 pm on the specified submission date. Work submitted after the submission time and date will be returned unmarked and will be assigned zero marks, unless a doctor’s certificate is presented. Marked assignments will be returned at a suitable lecture. Assignments that have not been collected by students will be available for collection from the box marked ‘Mining Geomechanics’ in room N135d.
