Tailings Impoundment Stability

noun

Pronunciation: /ˈteɪlɪŋz ɪmˈpaʊndmənt stəˈbɪlɪti/

The structural integrity and geotechnical safety of engineered containment systems that store fine mineral waste products after ore processing. Stability assessment evaluates dam construction quality, seepage rates, slope angles, and long-term consolidation to prevent catastrophic failure.

Plain English

The ability of mining waste storage dams to remain structurally sound and prevent dangerous failures or leaks.

Etymology & History

Origin languageEnglish
Roottailings (Middle English taille, to cut) + impoundment (impound + -ment) + stability (Latin stabilis)
First recorded use1980s
Usage frequencyCommon

Usage

"Engineers conducted slope stability analysis to confirm the iron mine's tailings impoundment stability before approving the reclamation closure plan."

Style guide notes: Maintain distinction between 'stability' (static condition) and 'stabilization' (active process to improve stability).

Frequently Asked Questions

What factors determine tailings impoundment stability?

Key factors include dam height, slope angle, foundation conditions, seepage control, and material consolidation rates.

How often should impoundments be inspected?

Regulatory requirements typically mandate quarterly to annual inspections, with more frequent monitoring during wet seasons.

Why Test Candidates on This?

Essential for assessing closure readiness and long-term liability risk at mining sites.
