MINING –
Open pit slope design focuses on balancing safety, stability, and economic efficiency, involving geotechnical data analysis, slope modeling (bench/overall), and numerical analysis to determine optimal pit angles. Key aspects include geological mapping, managing water, and using software for slope stability assessment.
Fundamentals of Pit Slope Design
- Geotechnical Characterization: Crucial data includes rock mass strength, structural geology (faults/fractures), and hydrogeology.
- Slope Geometry: Components include bench height, bench face angle, berm width, inter-ramp angle, and overall pit slope angle.
- Failure Mechanisms: Slopes must be designed to withstand failures like planar sliding, wedge failure, toppling, and ravelling.
