Highwall Reclamation
nounPronunciation: /ˈhaɪwɔːl ˌrɛkləˈmeɪʃən/
The process of stabilizing, reshaping, or removing steep rock faces (highwalls) remaining after surface mining operations to prevent rockfall hazards and erosion. Techniques include slope reduction, benching, or controlled blasting to create stable angles.
Plain English
Stabilizing or reshaping the steep rock faces left behind after surface mining to prevent collapse and erosion.
Etymology & History
Usage
"Highwall reclamation required blasting the 60-meter rock face into stable 2:1 slopes before vegetative stabilization could begin."
Style guide notes: Clarify final slope angles (e.g., 2:1 or 1.5:1) when describing highwall reclamation results for technical accuracy.

Frequently Asked Questions
Why are highwalls hazardous in abandoned mines?
Steep rock faces are unstable and prone to rockfall, creating safety hazards and triggering erosion that impacts surrounding areas.
What methods are used to reclaim highwalls?
Controlled blasting reduces slope angles, benching creates terraces, and scaling removes loose rock to achieve long-term geotechnical stability.
Why Test Candidates on This?
Important for assessing physical hazard remediation and understanding slope engineering principles in surface mine closure.
