Contour & Backfill Open Pit

Bulk backfilling and GPS-controlled landform shaping of open pit areas to achieve regulatory-approved final landform designs as part of mine closure.

Planned material placement in staged lifts to maintain batter stability. GPS machine control was used throughout the contouring phase to match the approved landform design precisely, with regular survey comparisons to confirm progress.

Achieving approved pit backfill landform designs requires bulk material placement sequenced to avoid unstable batters, followed by precision contouring to match approved designs. Works must satisfy geotechnical and regulatory requirements.

Completed pit backfill and contouring to the approved final landform design, progressing the client's mine closure programme and satisfying all regulatory landform requirements for pit rehabilitation.
