The Minpraxis Tester provides geotechnical parameters critical to mine design

Continuous compression strength measurements allow subtle differences in veining, alteration and lithology type to be captured and related to strength. Understanding the role of veining in rock mass strength has been shown to be critical at many operations, influencing mine design, stability assessments, and ground support strategies.

The MPT provides geotechnical parameters along samples, including:

  • Point Load Test Index (IS50)
  • Unconfined Compressive Strength (UCS)
  • Indirect Tensile Strength

Geotechnical models are the cornerstone of mine design

Most geotechnical models rely on sparse, selectively chosen data, creating gaps in rock mass understanding. As a result, they often underperform and fail to predict geohazards.

The MPT measures strength continuously along core runs, capturing weaker zones that are often excluded from traditional test programs.

The MPT measures the strength of samples directly and continuously

With the MPT’s high-resolution strength measurements on half-core samples, variability in rock strength with depth is accurately captured and assessed.
