mine pool
nounPronunciation: /maɪn pul/
Accumulated groundwater and surface water in abandoned underground mine workings. Often contains dissolved metals and requires ongoing monitoring and treatment.
Full Definition
A mine pool forms when groundwater and surface water accumulate in the void spaces of abandoned underground mines after pumping operations cease. These water bodies typically develop complex hydrochemistry as water interacts with exposed rock surfaces, abandoned equipment, and mining residues over time. Mine pools can range from relatively clean water suitable for beneficial uses to highly contaminated water requiring treatment before discharge. The water level in mine pools may fluctuate seasonally and can eventually overflow through natural or constructed discharge points. Understanding mine pool hydrology and chemistry is crucial for long-term environmental management and determining appropriate reclamation strategies.
Plain English
The water that fills up old underground mines after they're abandoned, which can be clean or polluted depending on what minerals it touches.
In Editorial Context
A critical element in mine reclamation stories that helps explain ongoing environmental challenges and the need for long-term monitoring and maintenance.
Etymology & History
Terminology developed as mining operations expanded and hydrogeological understanding of mine flooding improved.
Originally descriptive term that became technical terminology with increased environmental regulation.
Usage
"Quarterly sampling of the mine pool showed improving water quality trends following implementation of passive treatment systems."
Usage note: Distinguish from surface impoundments or tailings ponds which are different water bodies.
Context: hydrological assessments, water quality monitoring, environmental compliance
Region: international
