This assessment is designed to strengthen your understanding of rock characterization and how to measure the strength of rocks. You will need to carefully review the course material and answer the questions in the assignment. This assignment will cover work detailed in the first three weeks of the unit. A marking criteria sheet is also available in the assignment link. Use this sheet to check that you have addressed all assignment requirements.

To achieve this, you will need to:

• Review the detailed assignment questions found in Moodle.
• Review relevant literature (textbooks, websites, etc.) to understand better the processes and procedures associated with sampling and testing rocks.
• Research the primary literature to locate relevant current primary sources (scientific journal articles written in the last ten years)
• Complete the assignment questions in your own words, effectively using the sources of information.

Your assignment should be produced electronically using word processing and spreadsheet software. Submit your work through the assessment link on Moodle.

Note: All submissions are processed through the similarity detection software Turnitin. You must ensure all the work is your own, per University requirements. Correctly reference all sources of information using the CQU Harvard referencing style guide. 

Structure

Cover Page showing unit code and name, student name and number, date, assignment number, lecturer, and university. An interesting picture related to the assignment work (cite and reference source). Correctly formatted table of contents, including a page for figures and tables. Include page headers and footers. State the assignment question at the beginning of each answer to give context to your answers. Include a reference list at the end of the assignment.

Content 

For calculation-based questions, ensure formulae and workings are shown in sufficient detail to clearly explain how the answer was derived. Include screenshots of spreadsheets as figures within the text of your answer, where required. Also, include a spreadsheet as a separate submission. Ensure formulae are included in the spreadsheets so that you can enter different values to check the sensitivity of the answer. Formulae included in the spreadsheet need to be accessible for marking. Answers should show correct units of measurement, e.g. (m, MN, m², tonnes, m³, ^oC, etc.).

Where appropriate, include clearly labelled diagrams detailing such things as,

• the dimensions of equipment and excavations
• angles of slopes
• coal thickness and overburden dimensions
• shapes of underground openings
• geometry of samples

For descriptive answers, use clear, coherent sentences. Ensure photographs, pictures and diagrams are correctly labelled and introduced within the preceding text. Use in-text citations and correctly reference all sources of information. Please include at least one reference from a journal paper from the CQU library (do not reference it as a webpage). Use mining terminology correctly. A more detailed and specific marking criteria sheet will be available to download from within the assignment link on Moodle.

This assessment will strengthen your understanding of the time-dependent behaviour of rock, the measurement and analysis of stress in the rock, and the classification of a rock mass. You will need to carefully review the course material and answer the questions in the assignment. This assignment will cover the unit's material detailed in weeks 4 to 6. A marking criteria sheet is also available in the assignment link. Use this sheet to check that you have addressed all assignment requirements.

To achieve this, you will need to:

• Review the detailed assignment questions found in Moodle.
• Review relevant literature (textbooks, websites, etc.) to gain an understanding of the time-dependent behaviour of rock, the measurement and analysis of stress and the classification of rock mass
• Research the primary literature to locate relevant current primary sources (scientific journal articles written in the last ten years)
• Complete the assignment questions in your own words, using reliable sources of information effectively.

Your assignment should be produced electronically using word processing and spreadsheet software. Submit your work through the assessment link on Moodle.

This assessment is designed to deepen your knowledge of the application of ground support, ground monitoring, and excavation design to mitigate the risk of ground failures in various mining situations. You will need to carefully review the material in the textbook and answer the questions in the assignment. This assignment will cover the unit's material detailed in weeks 7 to 12. A marking criteria sheet is also available in the assignment link. Use this sheet to check that you have addressed all the assignment requirements.

To achieve this, you will need to:

• Review the detailed assignment questions found in Moodle.
• Review relevant literature (textbooks, websites, etc.) to better understand the risks of ground failure associated with mine excavations.
• Research the primary literature to locate relevant current primary sources (scientific journal articles written in the last ten years)
• Complete the assignment questions in your own words that make effective use of the sources of information.

Your assignment should be produced electronically using Word and Excel documents. Submit your work through the assessment link on Moodle.

The practical assessment will consist of a laboratory session or a visit to a mine site. The timing of the residential school will depend on the availability of a mine site visit. The laboratory session will be held during vacation week if a mine visit is not possible.

Part 1. Students will complete a laboratory session using a point-load rock testing machine and following a worksheet.

Part 2. Students will present their findings from their laboratory session to other students and available staff.

Alternatively, students visiting mine sites will present a rock engineering issue from the mine site to other students and available staff.

Students will be assessed on their ability to,

• work as part of a team
• Comply with instructions from the mine site or laboratory personnel.
• Demonstrate an understanding of rock mechanics.
• Participate in risk assessment discussions.
• Present their findings

The objectives of developing a learning portfolio include,

1. Provide the student with an opportunity to reflect on their learning.

2. Record work and reading not presented or assessed as part of the submitted assignments.

3. Provide students with an opportunity to discuss their learning experiences online.

4. Provide students with an opportunity to record and demonstrate evidence of all the learning outcomes detailed for this unit, particularly teamwork, cultural sensitivity and ethical values.

The learning portfolio will consist of two components,

i) a study diary, including reflections on learning

ii) evidence of learning outcomes.

A learning portfolio template will be available in the assignment link on Moodle. Detailed examples explaining what must be recorded in each element of the learning portfolio will also be available on Moodle.

       The assessment criteria for your learning portfolio will include,

•             regular weekly entries in the study diary
•             written entries about how the learning outcomes have been met
•             records of interactions that seem relevant to this unit, 

       Interactions may be with the lecturer, other students or work colleagues. Interactions may be Zoom sessions, telephone conversations, emails, blog postings, or face-to-face meetings. Submit updates to the learning portfolio with each assignment submission. Achieving a Pass for this assessment requires some evidence recorded against each learning outcome.
