Township of Brock
a Multi-Phase Initiative
This rehabilitation project narrowed in on five hectares of land within the 343.5-hectare pit site. The multi-phase initiative began in August 2019 when 4,000 cubic metres of overburden and 6,000 cubic metres of topsoil was stripped from the northeast portion of Sunderland Pit’s Phase 1B rehabilitation site. The material was removed to uncover plant feed material and transferred to the adjacent southwest area to facilitate the rehabilitation.
Contouring the land
A D51 Kamatsu dozer was then used to grade and contour the land to blend it with the surrounding environment. Topsoil was then applied to a minimum average thickness of 100 mm. Finally, the area was seeded with a 350kg mix of annual rye, buckwheat, alfalfa, crown vetch, white clover and tall fescue. For phase 2, the existing pit floor was graded and sloped in a southern direction. A total of 4,000 cubic metres of topsoil was applied and seeded, at a rate of 125kg, using the same mix as the previous phase.
