Contour Grading
noun phrasePronunciation: /ˈkɑːntʊr ˈɡreɪdɪŋ/
The earthmoving technique of reshaping mined slopes using natural landform contours to enhance visual integration, reduce erosion, and facilitate natural drainage patterns. This approach mimics pre-mining topography and improves long-term slope stability.
Plain English
Reshaping mine slopes to look natural and prevent erosion using contoured landforms.
Etymology & History
Usage
"Contour grading transformed the steep mine wall into a naturalistic slope that blends seamlessly with surrounding terrain."
Style guide notes: Hyphenate as compound modifier: 'contour-graded slopes'; do not use 'contoured grading'.
