Large Diameter Borehole (2m dia.)
We have a requirement to make a 2 metre diameter lined borehole to a depth of 200 metres to provide access to an underground mined area. Ground conditions are generally soft, not hard rock.
I am unable to find a drill rig manufacturer or source equipment able meet this requirement
Any ideas or advice will be much appreciated!
