Assessment submission dates are listed in Section 6 Course Assessment.
Students need to confirm the actual date of the formal exam for the course.
Teaching & Learning Methods
1. Activity-based learning: This course utilises activity-based learning methods. Activity-based learning is different from the traditional face-to-face lecture format of a lecturer in the front of the class doing most of the talking. The interactive sessions could include a traditional lecture using a PowerPoint presentation or a tutorial session or a group activity to reinforce the learning.
2. Lectures and tutorials: Project work will be supported with weekly consultative and information-sharing session. The content of these are aligned with the projects to help
COURSE OUTLINE 8
MINE3630 ROCK BREAKAGE
students. Although this is an activity-based course, it is a requirement that all work is conducted within the School.
3. Group work: Each project will have a number of focus areas. Members of a group may elect to work on a topic of the project they feel more comfortable with, but should integrate their work into the whole project. This should be reported back at their team meetings. A peer review will be required to ascertain the performance and contribution of individual students to the group project. Marks can be deducted from the underperforming students and allocated to other group members. If a student makes no effective contribution to the group project then that student can be awarded zero marks for that project assignment. This might result in failure in the course.
4. Effective Communication: One of the most effective means of learning is to effectively communicate what has been learnt. Part of the assessment in this course will be determined by how effectively the results are communicated. There are a number of opportunities for this in the form of presentations and final reports. The process of writing reports, brainstorming within a design team, peer assessment, preparation and presentation of report both in front of an audience and in report form, requires clarity of thinking, defending and revising a design and analysing the risks inherent in a project.

Assessment requirements
Before starting and again prior to submission of each assignment task, the student is advised to read the requirements for the particular assignment as detailed in the Assessment Criteria whenever it is made available. Also prior to submission, the student is recommended to make sure they have have read and understood the following.
Declaration of Academic Integrity contained on the Assignment Coversheet;
Assignment Submission requirements detailed in the University Policies section; and
The School's Policy on Assignment Submission a copy of which can be found on the School's website.
In the case of electronic submission of an assignment, note in particular the requirements in the School Policy that only a single PDF document should be uploaded with the file consistent with a specific file naming convention. Submission requirements for all assignments are listed in Sections 4 and 7 of the Course Learning Guide.
COURSE OUTLINE 10
MINE3630 ROCK BREAKAGE
Assignment preparation
The submission must be prepared in the form of a formal report that includes a list of reference sources cited in the report, prepared in accordance with the report writing standards of the School as contained in the MEA Report Writing Guide for Mining Engineers. A copy can be obtained from the UNSW Bookshop or downloaded from the School website. It is strongly recommended that the School Report Template is used in preparing a written assignment. The template is available for download from LTMS. Note: as this template already incorporates the required the Student Declaration Form, a student does not need to separately append a signed copy of coversheet to their assignment when using this template.
Assignment attachments
Each assignment submitted for assessment must be attached with:
an official School Coversheet at the front of the assignment; and
the requisite Assessment Criteria form at the end of the assignment with the self-assessment completed by the student.
If either or both of these are not attached then the assignment will be deemed non-compliant with the assessment requirements. A non-compliant submission may not be marked and zero marks may be awarded for that assessment item. In any case a minimum 5% of the total marks will be forfeited for that assignment.
Assignments due date and time
If not otherwise stated the default deadline for submission of an assignment is 9:00am on Monday in the nominated week. If the Monday coincides with a Public Holiday then the due date is the next business day in the nominated week. Penalties will apply for non-conformance with Assessment Deadlines as detailed in the Course Outline. Early submissions are suggested if the student will otherwise be absent on the due date of submission.
Non-compliant Submissions
Penalties will apply to non-compliant assignment submissions, that is a submission that does not meet any or all of the requirements as detailed in the School's Policy on Assignment Submission and/or the later section on Assignment Submission in this Course Outline
Some examples of non-compliant assignments and the penalties that will apply are as follows.
The assignment document does not contain a signed copy of the Student Declaration Statement. Penalty: assignment not marked.
The assignment document does not contain at the end of the document a completed self-assessment by the student using the provided Assessment Criteria. Penalty: 5 marks.
The assignment file is not a single PDF document. Penalty: assignment not marked.
11 COURSE OUTLINE
MINE3630 ROCK BREAKAGE
The assignment file name is not fully consistent with the required file naming convention. Penalty 5 marks.
Quizzes
The three quizzes in the course will be conducted on-line quiz using Moodle in the School of Mining Engineering Computer Laboratory, OMB Rm 48.
The quizzes will be scheduled during the normal lecture period or either on a Thursday or Friday in the nominated week between 10am and 2pm. The duration of each quiz will vary between 30 and 50 minutes. Students should make provision in the diary to be available during these periods in each of the nominated weeks. Non-attendance at the Quiz will result in a zero mark. No supplementary quizzes will be scheduled.
The Quiz will cover the various learning outcomes as defined in the Course Outline and the material outlined in the Learning Guides.
The Quiz will include a combination of multiple answer, short answer and calculation style questions selected at random from a bank of questions.
Normal university regulations for examinations will apply to the Quiz.
Students must also bring to the Quiz a Quiz Summary Sheet (QSS). Preparation of the QSS is regarded as a key part of the learning process and so students are strongly encouraged to prepare their own QSS. Requirements of the QSS are:
o it must be the student’s own work;
o it must be a single A4 sheet of paper with notes placed on both sides of the sheet;
o the sheet must contain only handwritten notes and diagrams. It must NOT contain any typed, photocopied or computer generated information;
o it must be the individual student’s own work written in pencil and/or pen. A photocopy is NOT allowed;
o there are no constraints on the size or amount of information that can be included; and
o the student’s name and signature must be placed in the top right hand corner of the QSS with the statement “I declare this QSS is all my own work.”.
If a QSS does not comply with all of these requirements then it may be confiscated and the student will not have recourse to the QSS during the Quiz. Academic Misconduct procedures may also be applied.
The QSS must be surrendered at the end of the Quiz. The QSS will be checked but will not be assessed, so students can elect to submit a blank QSS. Students who do not submit a QSS will get zero marks for the Quiz.
The QSS will not returned to students. Students are advised to make a copy for their own use.
Machine Mining Quiz – summative assessment. As there will be only one exam component for this module, the Machine Mining quiz will be a summative assessment, that is there will not be an opportunity to correct an incorrect answer. The duration of this quiz will be approximately 50 minutes.
Blasting Quizzes – formative assessment. These are designed to be formative assessment, that is to contribute to student learning. When a student provides an incorrect answer to a question, the student will be given a brief explanation of the problem and may attempt one or more replacement questions. Any student who achieves 80% or more correct answers overall in a quiz will be awarded the full 5% for that quiz. Any student who fails to achieve 80% or more correct answers in a quiz will be given a zero mark for that quiz. Students will be under time pressure, so familiarity with the material is crucial.
COURSE OUTLINE 12
MINE3630 ROCK BREAKAGE
Students should bring to the Quiz a calculator, pen and pencil, the Quiz Summary Sheet and their Student ID card. A blank sheet of paper for workings will be provided.
Group Project
See the section on Group Work - Peer Assessment in the section on University Policies for further details on the requirements and process of peer assessment in the group project assignment.
Formal Exam
An exam in the formal examination period at the end of semester will be held on material covered in the Drilling and Blasting modules of the course. The examination will be closed book, all necessary formulae will be provided on the exam paper.
13 COURSE OUTLINE
MINE3630 ROCK BREAKAGE
7. ASSESSMENT CRITERIA
Full marks for an assignment or examination question can be obtained where:
The numerical ‘result’ is substantiated by an ‘answer’ comprising a complete mathematical working with appropriate definitions, assumptions, explanations and sketch diagrams at each stage.
The result is numerically correct, with the correct units, magnitude and sign.
The appropriate number of significant figures have been reported in the result and the accuracy of the result has not been compromised by rounding errors.
Where appropriate, there is 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. These typical maximum marks apply where the following errors occur:
There is a minor calculation or transcription error, but otherwise the answer is satisfactory and the result is consistent and apparently reasonable: 70 to 90%
The answer is satisfactory but the result is compromised by one of more of the following: is inaccurate due to rounding errors, has incorrect or no units, has the wrong magnitude, has the wrong sign: 60 to 80%
There is a minor calculation or transcription error but, although the answer is satisfactory, the result is clearly unreasonable: 40 to 60%
The result is correct but there is little or no mathematical working with appropriate definitions, assumptions, explanations and sketch diagrams at each stage: 30 to 50%
The question has been misunderstood, an inappropriate mathematical working has been applied but the result is consistent and apparently reasonable: 20 to 40%
The question has been misunderstood, an inappropriate mathematical working has been applied and the result is clearly unreasonable: 0 to 30%
The input data have been transcribed correctly, but there has been no serious attempt to answer the question 0 to 10%
A descriptive answer, although substantially correct, is padded with waffle and irrelevant material: 60 to 80%
A descriptive answer is very brief and clearly deficient: 30 to 60%
A descriptive answer merely comprises a re-statement of the question with something like “… is very important” added at the end: 0 to 10%
The following assessment criteria provide both a framework for students when preparing major assignments in the course as well as a guideline for assessors when marking an assignment. The student is advised to review the relevant framework before undertaking their assignment.
COURSE OUTLINE 14
MINE3630 ROCK BREAKAGE
The criteria listed for each item of assessment and the descriptions contained therein are not intended to be prescriptive nor is it an exhaustive list. Rather it should be viewed as a framework to guide the student as to the type of information and depth of coverage that is expected to be evident in an assignment; the framework illustrates for example what would distinguish an excellent achievement from a poor achievement. The student should be cognisant that a range of factors are often being assessed in any one assignment; not just whether the final results are numerically correct. Consideration is given to other relevant elements that contribute to the Learning Outcomes of the course as well as the Graduate Attributes of the overall degree program. The student is cautioned against merely using the assessment criteria as a checklist. When assessing an assignment, elements in the framework will be examined in terms of quality and creativity. Hence ensuring all elements are merely covered in an assignment is often not sufficient in itself and will not automatically lead to full marks being awarded. Other factors such as how the student went about presenting information, how an argument was structured and/or the elements supporting a particular recommendation or outcome are also important. Finally the framework can also be used to provide feedback to a student on their performance in an assignment. Periodically the criteria are reviewed and updated, consequently changes may be made to the framework to improve their effectiveness in achieving both these objectives. Note: Reference to RWG in the assessment criteria refers to the MEA Report Writing Guide, and GTA to the AusIMM Guide to Authors.

8. UNIVERSITY POLICIES
Assignment Submissions
All assignments submitted for assessment in this course must be made in accordance with the School Policy on Assignment Submissions, hereafter in this subsection termed the Policy. Details can be found in the School Policies section of the School webpage at < www.engineering.unsw.edu.au/mining-engineering/school-policies>. Students are required to read the latest version of the Policy and be aware of the various requirements including submission requirements and academic integrity. Failure to adhere to the requirement and/or submit an assignment that is in full accordance with the Policy can result in forfeiture of all marks for that assignment by the student. An Assignment Coversheet must be attached to each assignment submitted for assessment whether the assignment is submitted in electronic or hardcopy form. The coversheet identifies the student, assignment, course and contains a declaration of academic integrity – see later section on Academic Honesty and Plagiarism. An assignment that does not contain a full and proper completed copy of the official coversheet for the assignment will be deemed non-compliant and not marked and the student will be awarded zero marks for the assignment. In the case where a hardcopy submission of an assignment has been permitted in the assignment briefing document then the submission requirements for hardcopy submissions as detailed in the Policy must be followed. The student must attach to the front of the assignment a completed and signed copy of the appropriately coloured Assignment Coversheet for the particular Course Convenor which in this case is LIGHT GREEN. A copy of the coloured Coversheet is available from the Course Convenor one week before the assignment due date. The assignment must be stapled in the top left hand corner or bound in an appropriate manner. Alternatively an assignment can be bound along the left hand margin with a plastic binding comb with a clear plastic front cover. Assignments must NOT be submitted in a protective plastic sleeve. Assignments which submitted electronically may be required to be submitted through Turnitin. Students are advised to retain a copy of every assignment submitted for assessment for their own record either in hardcopy or electronic form. From time to time assignments may be mislaid and a student can be asked to re-submit.
Group Work – Peer Assessment
Group work is a key Graduate Attribute in the MEA program. As such it is integrated into the assessment activities of many MEA courses to determine whether a student has satisfactorily attained one or more of the Learning Outcomes. An important indicator of a student’s performance and of their contribution to the group’s overall performance is reflected in the results of a formalised system of peer review. The Course Convenor uses these results and other factors in their determination of an individual student’s result for the assignment.

For further details see Peer Assessment in the School Policies section of the School webpage. Students should be aware that participation in the peer review process is compulsory and that failure to do so can result in withholding of marks and/or zero marks being allotted to the student for that assignment.
Late Submission of Assignments
In the normal course of events late submission of an assignment will automatically result in a zero (0) mark being awarded to the student/project team for the assignment. The onus is on the student to ensure each course assignment is submitted on-time during normal business hours and no later than the required time on the due date as stated in the relevant assignment briefing document. For further details see Late Submissions in the School Policies section on the School webpage. See also the later section on Adverse Performance – Special Consideration.
Course Results
For details on assessment policy, assessment process and an explanation of course results, see the Assessment Policy section in the School Policies section on the School webpage. In some instances a student’s final course result may be withheld and not released on the usual date. This is indicated by a course grade result of either:
WD – which usually indicates that the student has not completed one or more items of assessment or there is an issue with one or more assignment; or
WC – which indicates the student has applied for Special Consideration due to illness or misadventure and the course results have not been finalised.
In either event the onus in on the student to contact the Course Convenor as soon as practicable but no later than five (5) days after release of the course result. Failure to take this action will normally result in forfeiture of any additional assessment granted to the student. In which case the student may be required to re-submit an assignment or re-sit the final exam. Failure to contact the Course Convenor within the stated period may result in the student failing the course. If contact has not been made and/or course assessment has not been finalised by commencement of the following academic semester then the grade will be automatically altered to a course grade of NC (course not completed) in Week 2. This will require the student to re-enrol in the course at some later time.
Adverse Performance – Special Consideration
In cases of illness or other extenuating circumstances that may have adversely impacted on a student’s performance in a course, it is recommended the student apply to Student Central for Special Consideration. It is incumbent on the student to contact the Course Convenor immediately following lodgement and acceptance of the Special Consideration preferably in person and no later than one week from lodgement. Failure to make contact can result in forfeiture

for any consideration and subsequent finalisation of the mark for the assignment and/or course. Only following acceptance and official notification from the University, will any decision be made by the Course Convenor as to an appropriate response based the circumstances outlined by the student. For further information, see Special Consideration – Illness and Misadventure within the section on UNSW Policies on the School webpage.
Academic Honesty and Plagiarism
The University has certain expectations in terms of academic behaviour related to study and research. This is expressed in the University Policy on Academic Misconduct. Students should be aware of and understand this Policy. For further information, see Academic Misconduct and Plagiarism in the section on UNSW Policies on the School webpage. Plagiarism is one form of Academic Misconduct. It is the presentation of the thoughts or work of another as one’s own1. Examples include:
direct duplication of the thoughts or work of another, including by copying work, or knowingly permitting it to be copied. This includes copying material, ideas or concepts from a book, article, report or other written document (whether published or unpublished), composition, artwork, design, drawing, circuitry, computer program or software, web site, Internet, other electronic resource, or another person’s assignment without appropriate acknowledgement;
paraphrasing another person’s work with very minor changes keeping the meaning, form and/or progression of ideas of the original;
piecing together sections of the work of others into a new whole;
presenting an assessment item as independent work when it has been produced in whole or part in collusion with other people, for example, another student or a tutor; and,
claiming credit for a proportion a work contributed to a group assessment item that is greater than that actually contributed2.
Submitting an assessment item that has already been submitted for academic credit elsewhere may also be considered plagiarism. The inclusion of the thoughts or work of another with attribution appropriate to the academic discipline does not amount to plagiarism. Students are reminded of their Rights and Responsibilities in respect of plagiarism, as set out in the University Undergraduate and Postgraduate Handbooks, and are encouraged to seek advice from academic staff whenever necessary to ensure they avoid plagiarism in all its forms. The Learning Centre website is the central University on-line resource for staff and student information on plagiarism and academic honesty. It can be viewed at < www.lc.unsw.edu.au/plagiarism >.

The Learning Centre also provides substantial educational written materials, workshops, and tutorials to aid students, for example, in:
correct referencing practices;
paraphrasing, summarising, essay writing, and time management;
appropriate use of and attribution for, a range of materials including text, images, formulae and concepts.
Individual assistance is available on request from The Learning Centre. Students are also reminded that careful time management is an important part of study and one of the identified causes of plagiarism is poor time management. Students should allow sufficient time for research, drafting, and the proper referencing of sources in preparing all assessment items. In line with this university expectation, a student must attach to each assignment a fully completed official coversheet which contains a declaration of academic integrity. The following is an example of an assignment coversheet (note: changes to the assignment may occur from time to time).
[An example extract from an Assignment Coversheet] ACADEMIC REQUIREMENTS Before submitting this assignment, students are advised to review:
the assessment requirements contained in the briefing document for the assignment;
the various matters related to assessment in the relevant Course Outline; and
the Plagiarism and Academic Integrity website at < http:/www.lc.unsw.edu.au
/plagiarism/pintro.html > to ensure they are familiar with the requirements to provide
appropriate acknowledgement of source materials.
If after reviewing this material there is any doubt about assessment requirements then in the
first instance the student should consult with the Course Convenor and then if necessary with
the Director – Undergraduate Studies.
While students are generally encouraged to work with other students to enhance learning, all
assignments submitted for assessment by a student must be their entire own work and they
may be required to explain any or all parts of the assignment to the Course Convenor or other
authorised persons. Collusion is where another person(s) assists in the preparation of an
assignment without the consent or knowledge of the Course Convenor.
Plagiarism and Collusion are considered as Academic Misconduct and will be dealt with
according to University Policy.
STUDENT DECLARATION OF ACADEMIC INTEGRITY I declare that:
This assessment item is entirely my own original work, except where I have
acknowledged use of source material [such as books, journal articles, other published
material, the Internet, and the work of other student/s or any other person/s].
This assessment item has not been submitted for assessment for academic credit in this, or
any other course, at UNSW or elsewhere.
I understand that:
The assessor of this assessment item may, for the purpose of assessing this item,
reproduce this assessment item and provide a copy to another member of the University.
The assessor may communicate a copy of this assessment item to a plagiarism checking
service (which may then retain a copy of the assessment item on its database for the
purpose of future plagiarism checking).

Continual Course Improvement
Periodically the process of course evaluation is undertaken. One aspect of this evaluation is feedback from students gathered by various means including:
UNSW's Course and Teaching Evaluation and Improvement (CATEI) which is an anonymous, on-line survey system.
Student feedback is taken seriously, and continual improvements are made to the course based in part on such feedback. Significant changes that are made to a course as a result of such student feedback will be communicated to students by the Course Convenor at commencement of semester when the course is next run.
Correspondence and Email Messages
University policy states that official correspondence with a student will be made using the university provided email address and that it expects students will regularly check their official university email account. The School assists in this by providing free access to computing facilities and the internet. In line with this policy, messages will be sent to students through their LTMS account. Students can retrieve messages from the mailbox in each LTMS course account.
Administrative Matters
Students should ensure they are familiar with the various policies related to expectations of students. Links to the Policies can be found on the School web page. Equity and diversity: those students who have a disability that requires some adjustment in their teaching or learning environment are encouraged to discuss their study needs with the course convener prior to, or at the commencement of, their course, or with the Equity Officer (Disability) in the Equity and Diversity Unit (< www.equity.unsw.edu.au/disabil.htm >). Issues to be discussed may include access to materials, signers or note-takers, the provision of services and additional exam and assessment arrangements. Early notification is essential to enable any necessary adjustments to be made. Information on designing courses and course outlines that take into account the needs of students with disabilities can be found at < www.secretariat.unsw.edu.au/acboardcom /minutes/coe/disabilityguidelines.pdf >.
