- Kinematic Analysis Tools for Slopes

From

0

KATS (Kinematic Analysis Tools for Slopes) is a tool developed by Itasca that assesses instabilities caused by day-lighting wedges and planar failures formed when different structural sets interact with the orientation of a given slope. KATS main application is for bench-berm scale analysis, which is understood as a first step in the mining slope design process for moderate and competent rock masses. It is also possible to perform a kinematic analysis in inter-ramp scale.

Unlike other tools currently available on the geotechnical analysis market, through a single automated process KATS performs a probabilistic or deterministic assessment of the behavior of a large number of slope configurations defined by many structural domains and many orientations and geometries of the slope. The results from the analysis can be provided using a variety of parameters, such as loss of crest, spill lengths, bench face angle distribution, etc. All these results allow a geometric definition of the interramp angles (IRA) that achieve the acceptability criteria defined by the operation from the point of view of stability and safety of personnel and equipment.

  • Very quick analyses (a few minutes of computer time for a full open pit)
  • Simple and easy to learn
  • Most inputs are readily available at mine sites
  • Can be calibrated given the performance of the slopes
  • Estimates the spill length of the failure mode (not available in other commercial software)
  • Can apply a probabilistic approach to produce cumulative frequency analysis (CFA) charts (not available in other commercial software), which is a typical methodology for bench scale design

  • Cumulative frequency curves (per each analyzed orientation):
    • Volume
    • Spill length
    • Backbreak
    • Effective bench face angle
  • Radar chart with (post-processed in Excel):
    • Recommended inter ramp angles
    • Recommended berm width
    • Expected Backbreak
    • Expected effective bench face angle
