    Craig used this type of rig (together with truck mounted) with both wash drilling and/or diamond coring depending on location, geology and depth needed. Boart Longyear provided the drillers.

    His projects involved drilling 50-400m deep holes (about 6 to date, and several more planned) to install downhole seismometers and tiltmeters at Auckland, Taranaki and Ruapehu for earthquake and deformation monitoring. 

    Mostly Craig is not interested in the hole, not the rock that comes out of it, as the aim is to install instrumentation rather than extract geologic information - although the holes are still logged geologically but not to any great detail.

    He also used existing abandoned waterwalls to install downhole seismic instruments - particularly in Auckland - so he is interested in knowing where such holes exist. He has in the past used a database from Auckland University to help find such holes.

     

     

     

    NOTE: Add a picture of the equipment... possibly, in addition to this, add a link to (or some info about) main technical specs of the actual piece of kit
