Formatted abstract
The objective of this study is to develop a final rehabilitation profile for haulage ramp 9. This ramp will be sufficient to act as a self-sustaining habitat for conservation purposes.

Over the past decade environmental awareness has become a very important issue within the community and mining industry. Companies are obliged to reclaim land to its pre-mining standard or an improved state. Generally, upon closure of a mine site haulage ramps will remain as a final void. Xstrata’s Oaky Creek Mine and Curragh Mine are the only two sites in Queensland who are known for their established haulage ramp reclamation. The mining industry as a whole is obligated to maintain the highest standard of environmental management possible. Furthermore, they should endeavour to improve on current environmental practices beyond their legal responsibility. This may be through haulage ramp reclamation or some other means.

Curragh Queensland Mining Pty Ltd’s operations are dictated by legislative and regulatory requirements comprising: The Mineral Resources Act 1989, Environmental Protection Act 1994, and the Water Resources Act 1989. The final rehabilitation profile satisfies each of the above-mentioned documents. Ramp 9 will be used as a water storage facility and will be divided into two sections by a 160m RL dam wall. The upper section of the ramp will hold an estimated 15ML of water and the bottom region will be built up to the 160m RL level to allow water to by-wash into the pit (final void). Slope angles will be limited to less than 25% within ramp voids and less than 10% for dragline spoil piles. Temporary graded banks will be installed to prevent erosion in the early stages of rehabilitation. Additional material will be transported into the lower section of the ramp from an adjacent pit. Reshaping of reclamation spoil will be by means of a dozer and scraper fleet.
