J&S Drilling have completed 4 separate QLD gold mine drilling programmes over the past 12 months at an underground gold mine in central QLD. All 4 campaigns have been very successful and have had outstanding results.

Air hammer & Air rotary drilling

2 of the 4 drilling programmes consisted of Air hammer & Air rotary drilling techniques to identify ground water levels and quality. The borehole depths ranged from 10m-78m. Air chip and water samples were taken in 1 meter intervals and laid out for the geologist to log the structure. Water samples were also taken on each rod change to ascertain flow rate and water quality. This allowed J&S Drilling to design monitoring bores, with both 50mm diameter PVC and 100mm diameter PVC around the information gained from the drilling. All the bores were completed by QLD Class 1 & 2 licensed drillers in accordance with the ‘Minimum Construction Requirements for Waterbores in Australia Edition 3 Guidelines‘.

HQ & PQ coring

QLD Gold Mine - core sample

The remaining 2 programmes were carried out utilizing casing advancing and HQ & PQ coring techniques for a geotechnical investigation around a tailings dam. The purpose of the geotechnical drilling was to obtain core samples to design monitoring and dewatering bores based on the fractures and water zones ascertained through the core samples. These core holes were up to 30m. The core was marked out, placed in PVC splits and boxed. Photos of the core were taken for the clients records.  SPT samples were taken at intervals requested by the supervising engineer.

J&S Drillings professionalism and outstanding results allows them to get ongoing work with this client. J&S Drilling versatility and investment in various drilling techniques ensures no job is too difficult or un-achievable. The equipment is maintained and presented to the highest standard which allows J&S drilling to have constant production and minimal down time.
