Waste rock is rock that has to be removed to allow coal to be mined. Detailed design and planning for waste rock storage will occur after the pit design is complete and the mining technique has been determined. Teck’s objectives for waste rock storage are to:
Teck is committed to avoiding the placement of waste rock in the Fording River valley and the Chauncey Creek drainage. Specific locations for waste rock storage are still being considered. We are currently evaluating a combination of three options, as described below.
The Kilmarnock Creek drainage runs along the north side of Castle Mountain and contains past and current waste rock storage areas from Fording River Operations. The upper portion of the drainage area has not been directly affected by mining.
Another option is to store waste rock in another pit at Fording River Operations. When mining in the Eagle Pit is complete, Teck could store waste rock from FRX in this pit. This approach is called “backfilling” the pit.
The third option is to store, or backfill, waste rock from FRX into the FRX area pit(s). This option provides numerous benefits, but would not be possible until there is sufficient space in the pit.
