Mine Rehabilitation
The restoration of mined land — landforms, soils, vegetation, water — to a safe, stable condition suited to an agreed post-mining land use.
Definition
Mine rehabilitation is the restoration of the post-mined landscape to the intended post-mining land use: reshaping landforms, managing waste rock and tailings, re-establishing soil and vegetation, and ensuring water quality, so the site is safe, stable and non-polluting. Mine closure is the broader process of decommissioning at end of operations; completion is reached when the lease can be relinquished.

Overview
What it means
Good practice integrates closure planning from project design onward, undertakes progressive rehabilitation during operations, sets measurable completion criteria, and engages communities on post-mining land uses — from grazing and native woodland to higher-value alternatives such as renewables or recreation.
How it is used
Governed by mining law and guidance (e. g. , ICMM's Integrated Mine Closure Good Practice Guide, the ISO mine closure standard series); regulators approve closure plans and hold financial assurance until completion criteria are met.
Why it matters
Mining is a transient land use; rehabilitation determines whether its legacy is restored landscapes and community benefit or perpetual pollution and liability.

Review board
Comment on a specific line. Each reviewer stays separate until an editor accepts a merged draft.
Each person comments on the definition or overview in their own draft card, with role, evidence and suggested wording kept together.
AI can compare comments against the current text, flag conflicting claims, surface missing evidence and identify where reviewers agree.
An editor merges compatible suggestions into a draft change, checks sources, records disagreements and decides what can be published.
