Robertson Geo equipment was purchased by the University to collect data pertaining to mineral exploration, with a particular interest in iron mining as Brazil produces high volumes of some of the highest quality iron ore grades found anywhere on the planet.
The training goals included familiarization with safety matters, logging procedures, data acquisition, preventative equipment maintenance and data processing.
Students were trained on the following equipment: Mini Winch, Micrologger 2, High Resolution Acoustic Televiewer®, Iron Ore Density probe, 3-Arm Caliper probe, Natural gamma, Full Waveform Triple Sonic probe and GeoCAD® software
The first part of the training related to good logging practice in data acquisition covering safety, to both the logger and the equipment, securing the winch, tripod usage, correct centralisation of probes, depth setting and the use of radioactive sources. This training was conducted using the University’s onsite borehole giving the students first-hand experience of a logging operation.
The second part of the training covered routine and preventative maintenance with special attention being given to cablehead replacement and slip ring maintenance. Basic diagnostic procedures were also covered to enable troubleshooting of routine problems so that fixes could be applied in the field thereby reducing downtime to a minimum.
Finally, using the data acquired at the onsite borehole, students were guided through the full processing sequence using the GeoCAD® software. This included simple log curves, televiewer processing, semblance processing and the derivation of small strain moduli (Bulk, Shear and Young’s) from the density and velocity data.
