7.3.7 Potable water plant
Potable water is supplied by Camden Power Station and is capable of meeting the proposed mine’s potable
water requirements. The potable water is pumped from Camden Power Station via a 152mm diameter pipeline to
a 75 000 cubic litre reservoir / header tank located on Usutu Coal Colliery from where it is further reticulated for
mine use.
The potable water facility can supply water to the reservoir / header tank at a rate of 500 litres per hour if
required. Booster pumps could further increase this supply rate if required.
7.3.8 Mineral processing plant
The proposed mine will not be beneficiating coal, hence no coal processing or dense medium plants will be built
on site. Only existing infrastructure will be utilised.
Coal will be tipped over the grizzly or scalping screen, undersize material will pass through the grizzly that will
have an aperture of 600mm. The minus 600mm will enter the in-pit mobile crusher where it will be reduced to
minus 200mm. The minus 200mm crushed coal product will be directed via a transfer chute to an in-pit overland
conveyor that will transport the minus 200mm crushed coal to the existing Camden overland belt infrastructure.
Transfer of coal from the in-pit overland conveyor will be facilitated by transfer chute, with coal always being
tipped on overland conveyor B.
The minus 200mm crushed coal will be conveyed through Conveyor B to Conveyor C, through Conveyor D
where it will be transferred via a McNally to a double set of jaw crushers, where the minus 200mm coal is
crushed to a minus 40mm size fraction and conveyed via Conveyor E into Camden Power Station. Run of Mine
(ROM) coal loaded onto the stockpile area will be approximately 40mm.
7.3.9 Workshops, administration and other buildings
The existing Usutu Coal Colliery infrastructure will be used in the proposed mine operations. No new
infrastructure areas will be developed.
The following existing infrastructure facilities will be utilised:
• Existing main office block;
• Existing mine change rooms;
• Existing first aid station;
• Existing mine stores (2);
• Existing workshops;
• Existing hostels;
• Existing sub-stations
• Existing road infrastructure; and
• Existing sewage plant.
