GEOTECHNICAL TELEVIEWER INTERPRETATION

Used as a complementary source of data for the identification and orientation of structures.

A methodology has been developed that accurately evaluates the full suite of geotechnical properties of a rock mass from these surveys.

The process has been specifically developed to have application in diamond and percussion drill holes or existing open holes, to optimise geotechnical drilling programs.

Reduces the cost and time for data acquisition.

DILUTION RATING SYSTEM

The geotechnical properties that affect dilution are unique to each mine site.

DRS takes cognisance of the rock mass properties to allow estimation of dilution thickness.

DRS is calculated and calibrated for each mine site to develop a design chart.

This is lead to the prediction of dilution thickness.

ROCK BRIDGE SLOPE STABILITY

A new approach that estimates the ratio of rock bridge to geological structure.

Uses data from a three-dimensional rock mass model that is derived from geotechnical logging.

This method allows for both failure criterion to be applied simultaneously enabling a more realistic representation of the pit slope and more appropriate factors of safety and probabilities of failure.

The use of a 3-dimensional MRMM developed using calibrated data collected from drill core will give a much greater range of strength parameters for probabilistic analyses.

Geotechnical Domain Logging

Large volumes of data are collected during geotechnical investigations for mining projects but rarely is this done in a comprehensive manner that enables all aspects of the geotechnical environment to be evaluated.

The logging method is unique in that sufficient data is collected to enable the independent determination of all the major rock mass classification systems.

The logging system has been specifically developed to allow better and more precise appreciation of rock mass and structural conditions.
