Rotary Boreholes

Rotary Boreholes

Rotary drilling techniques are used to drill through rock quality deposits and can be either rotary open hole drilled (where only the cuttings are returned to the surface as fine rock chippings) or rotary core drilled (where solid rock cores are recovered).

Rotary rigs available include relatively small and mobile tracked rigs up to much larger truck mounted rotary drilling rigs that are capable of accessing most development sites.
