Mine Collapse Hazard
nounPronunciation: /maɪn kəˈlæps ˈhæzərd/
The risk that underground mine workings will fail structurally, potentially causing ground subsidence, sudden sinkholes, or shaft failures that endanger infrastructure and human life. Collapse hazards depend on mine depth, geology, support system deterioration, and hydrogeological changes post-closure.
Plain English
The danger that abandoned mine tunnels or shafts will fail and cause the ground above to collapse.
Etymology & History
Usage
"The mining engineer assessed the old coal mine for collapse hazards before clearing the site for residential development."
Style guide notes: Distinguish between subsidence (gradual) and collapse (sudden) when describing ground stability impacts.
