Mining Short Notes📝
WHY NEED REHABILITATION & RECLAMATION IN MINING LIFECYCLE?
The final stage in mining lifecycle are rehabilitation and reclamation. Many mines may be capable of producing economically for decades, but mining is still a temporary activity. Ideally, companies should start preparing for rehabilitation in the early stages of their lifecycle and form their plan for rehabilitation before they begin construction. Governments require assurance that operators have a plan and the funds needed to close the mine before they are willing to issue permits.
The detailed environmental studies that are conducted during the process form a major part of the plan for how the mine site will be rehabilitated.
A comprehensive rehabilitation program has many clearly stated objectives which may include:
· ensuring public health and safety
· minimising environmental effects
· removing waste and hazardous material
· preserving water quality
· stabilising land to protect against erosion
· establishing new landforms and vegetation
Mine rehabilitation plans can aim to renovate the site to varying degrees:
1. Remediate the contaminated area, including water.
2. Reclamation of the terrain, landscaping and topsoil replacement to make the land useful once again.
3. Restore any part of the ecosystem that was disturbed as a result of the mine.
4. Rehabilitate the site to a stable and self-rejuvenating state, either as it was before the mine was built or as a new equivalent ecosystem.
