benching
nounPronunciation: /ˈbɛntʃɪŋ/
A reclamation technique involving the creation of horizontal steps or platforms on steep slopes to reduce erosion and improve stability.
Full Definition
Benching is a slope stabilization method used in mine reclamation where steep cuts or highwalls are modified into a series of horizontal platforms or benches separated by vertical or near-vertical faces. This technique reduces the overall slope angle, minimizes erosion potential, and creates more stable conditions for revegetation. Benches are typically designed with specific width and height ratios based on soil type, climate conditions, and intended post-mining land use. The practice helps manage surface water runoff and provides accessible areas for maintenance activities.
Plain English
Cutting steep mine slopes into step-like levels to make them more stable and prevent landslides or erosion.
In Editorial Context
In reclamation articles, represents a key visual and technical concept often requiring clear illustration and explanation of both the construction process and long-term stability benefits.
Etymology & History
Developed from traditional quarrying and road construction techniques, adapted for mine reclamation as environmental regulations became more stringent.
Originally a mining operational term that evolved into a reclamation technique as the industry recognized the need for slope stability.
Usage
"The reclamation plan specified benching the 200-foot highwall into 20-foot intervals to achieve a stable configuration suitable for native grass establishment."
Usage note: Can be used as both noun and verb; context usually clarifies whether referring to the technique or the action.
Context: slope stabilization, highwall reclamation, erosion control planning
