Assignment
The desire to accelerate the closure of a surface coal mine in three to four years, rather than the typical five-year schedule, necessitated a significant amount of planning and implementation as full reclamation activities commenced.

Our Role
As upfront planning was taking place, Golder helped complete a revised grading plan to balance the cut-and-fill volumes in the final mining area and reduce the overall volume of material that would need to be moved. The approved grading plan incorporates significant geomorphic grading practices that help provide long-term drainage stabilisation, reduce maintenance, and supply topographic diversity.

The goal is to minimise material movement, and fulfill the regulatory and permit obligations for the post-mining configuration established by the government agency that oversees surface mining reclamation and enforcement. This involves assessing and quantifying reclamation tasks to be completed and assisting in allocating those tasks to the labor force and earthwork contractors.

Daily planning, budgeting, operational guidance and field project management to implement plans and track monthly reclamation progress has been provided. GIS mapping and compilation of soils data in a soil mitigation database are also being doncuted. Archiving this soils monitoring data is required to demonstrate soil suitability.

When reclamation earthworks are complete, environmental monitoring and maintenance will be required during the 10-year period required to achieve final performance bond release.
