FACILITIES MANAGEMENT: OPEN CUT COAL MINE

Multimedia Filtration (MMF), Brackish Water Reverse Osmosis (BWRO), Gravity Clarification (GC), Chlorination, Moving Bed Bioreactor (MBR)

Mining

Bowen Basin, Central Queensland

BACKGROUND

The owner of a metallurgical coal mine undergoing expansion near Blackwater in Central Queensland required the expertise of a specialist water and wastewater treatment contractor to manage its water treatment assets and guide the operations through a capital upgrade path to accommodate the mine life extension.

Covering an area of 12,600 hectares, and with a production capacity of 7Mt per annum of high grade coking coal required for steel production, this mine is currently sitting on an estimated 90 million tonnes of high grade coking coal, making it one of the largest of its kind in the world. Recent expansion to operations and processing capability will see the mine life extended to 2030 and beyond.

MAK Water was engaged by the owner to operate and maintain multiple potable water and wastewater treatment plants and replace an existing sewerage plant onsite. MAK Water was awarded a 3-year Operations Agreement to provide an operational team to maintain and operate all the water treatment plants onsite.

The Operations Agreement is for the provision of plant operation, technical support, onsite maintenance (both planned and emergency), and the supply of consumables required for normal plant operation.
