Secondary Porosity Development
nounPronunciation: /ˌsɛkənˈdɛri pɔˈrɑsɪti dɪˈvɛləpmənt/
The creation of additional pore space and permeability in rock and soil materials through chemical weathering, oxidation, and mineral dissolution during or after mining reclamation. This process affects groundwater flow patterns and contaminant transport in reclaimed mine sites.
Plain English
Creation of new tiny air and water spaces in rocks through chemical breakdown after mining.
Etymology & History
Usage
"Secondary porosity development in the backfilled mine void accelerated contaminant migration rates beyond initial groundwater models during the reclamation monitoring phase."
Style guide notes: Use in hydrogeological contexts; specify affected materials and mineral types.

Frequently Asked Questions
How does secondary porosity affect mine reclamation?
Increases water infiltration, alters contaminant pathways, requires revised groundwater models.
What causes secondary porosity in mines?
Mineral oxidation, acid dissolution, sulfide weathering, and chemical reactions in exposed materials.
Why Test Candidates on This?
Relevant for advanced hydrogeological assessment and long-term contaminant fate prediction.
