BHP: Mt Arthur Coal
Case 1JP
Environmental benchmarked water use at Mt Arthur Coal for BHP. The
project involved comparing coal handling and preparation plant water
usage with industry standards based on ROM per quantity of reused,
recycled and fresh water. CPP water usage trends were also forecasted.
Case 2The
site water classification and reporting practices were reviewed and
benchmarked against the Minerals Council of Australia Water Accounting
Framework and the practices of comparable industry operators.
Case 3Design
a surface drainage system for rehabilitated mined land. Define
catchments and design contour drains to direct surface runoff into
proposed and existing sediment dams. Size the proposed dams in
accordance with ‘Managing Urban Stormwater: Soils and Construction:
Volume 2E Mines and Quarries’. Design a 700 metre long rock lined drain
to convey runoff down a rehabilitated overburden emplacement. Identify
alternate drainage designs and channel armour. Prepare a design report.
