Acid mine drainage (AMD) formation prevention
noun phrasePronunciation: /ˈæsɪd maɪn ˈdreɪnɪdʒ ˌfɔːrˈmeɪʃən prɪˈvenʃən/
Preventive strategies and engineering controls implemented during mine reclamation to inhibit the oxidation of sulfide minerals and subsequent acid generation in mine materials. These methods include oxygen exclusion, pH buffering, and encapsulation of reactive materials.
Plain English
Techniques used to stop acidic water from forming at abandoned mine sites.
Etymology & History
Usage
"AMD formation prevention using alkaline covers was essential for the sulfide-rich tailings at this site."
Style guide notes: Use full acronym expansion on first mention; thereafter may abbreviate to AMD prevention.

Frequently Asked Questions
What causes acid mine drainage?
Sulfide mineral oxidation exposed to water and oxygen produces sulfuric acid and metal leaching.
How do covers prevent AMD formation?
Low-permeability covers reduce water and oxygen contact with reactive sulfide minerals in tailings.
Why Test Candidates on This?
Essential knowledge for environmental compliance and long-term water quality protection at reclaimed mines.
