- •
3D remote sensing and 2D digital trace mapping were undertaken at four rock slopes.
- •
New intensity parameters for rock bridges and blasting fractures are introduced.

Discontinuity persistence and probable rock bridge geometries are interpreted.
- •
Recommendations are provided for modified field investigation techniques.
