MINING OPERATIONS
The Cameby Downs Mine operates under and involves operation of an open cut coal mine, CHPP and rail load-out infrastructure.
Open cut mining continues to target the Juandah Coal Measures coal seams. The approximate depth of the open cut pits is estimated to be between 40 to 110 m below natural ground level, and the approximate maximum height of the waste rock emplacements is anticipated to be up to 45 m above natural ground level.
Vegetation Clearing and Topsoil Salvage.
Vegetation clearing and topsoil salvage will continue to be conducted in accordance with procedures outlined in the existing Cameby Downs Mine Plan of Operations.
Vegetation will be progressively cleared ahead of the active open cut and waste rock emplacement areas. Topsoil will be stripped prior to excavation of underlying overburden. Where the topsoil cannot be directly used for progressive rehabilitation it will be stockpiled for use at a later date.
Overburden and Interburden Removal and Handling.
Weathered overburden will continue to be removed using dozerpush, excavators and haul trucks where possible. Competent waste rock material will be drilled and blasted before being dozer pushed to in-pit spoil dumps and/or loaded to haul trucks and dumped in-pit and on out-of-pit spoil dumps consistent with current mining methods at the Cameby Downs Mine.
The boxcuts undertaken as part of mine development will require wast ........
