ENGIN 5515 - Tunneling and Mine Development - Engineering Assignment Help

Assignment Task

Team or individual: Students are encouraged to do this design project in team of two students voluntarily formed by themselves. However, a single person team is acceptable with neither bonus nor penalty marks. 
Deposit 1
A massive porphyry style deposit located at high altitude in West Papua. Average grade of the deposit is 0.5 g/t Au and 0.8 g/t Cu. The deposit has a UCS of 200MPa and is highly fractured; country rock is similar in nature. The deposit has a large foot print area 500m by 500m and is located 300m from surface and open at depth.

You are required to do a major underground mine development plan and the initial (first) underground development design, specifically as follows.

1. Of the mining methods you proposed for this deposit, decide a most adequate mining method-Sublevel stooping  and further propose an adequate annual production rate. (Key points to address in this part, (1) if the mining method is optimal and (2) if the production rate is adequate.)(5 marks)
2. Propose a mine development plan for the deposit. (Key points to address in this part, (1) if the plan is rational and (2) if the production rate can be facilitated.)(5 marks)
3. Select and Design one of the major underground developments to access the orebody (Key points to address in this part, (1) if the design is rational and (2) if it can facilitate the production rate required.) (20 marks). This part should include:

• Specify the development selected,
• Design its cross section to meet the production rate,
• Verify the cross section to meet the ventilation requirement,
• Excavation strategies and designs (including rock breakage, ventilation, mucking, drainage control and ground support designs), and
• Any other salient points.

Note: students should list any assumptions made.

Your report must be typed and finished in a professional manner with all references acknowledged, and bear in mind that a report such as this would not be complete without drawings, sketches, etc. Please note that COPY and PASTE is plagiarism and CLAIMING CONTRIBUTION TO A TEAMWORK is plagiarism if he/she has not made adequate contribution. 

Useful sources of information include the University library, websites, Mining Monthly and other journals.
