Pit wall stabilization
noun phrasePronunciation: /pɪt wɔːl ˌsteɪbɪlaɪˈzeɪʃən/
Engineering measures applied to the exposed rock and soil faces of surface mine excavations to prevent slope failure, erosion, and material raveling. Stabilization techniques include slope flattening, rock bolting, shotcrete application, and drainage installation to increase safety and long-term durability.
Plain English
Reinforcing and protecting the sloped sides of open pit mines to prevent collapse and erosion.
Etymology & History
Usage
"Post-mining pit wall stabilization was essential to prevent rockfall hazards in the reclaimed limestone quarry."
