| METHOD | HOLESIZE | DEPTH | RIG AIR | COMMENTS |
|---|---|---|---|---|
| RAB | 3 7/8” – 4” | 120 m | 600CFM / 250PSI | Will drill weathered horizon, ground conditions allowing, to 120 meters. |
| Aircore | 85mm – 87mm | 120 m | 600CFM / 250PSI | Will drill weathered horizon to 120 meters (Including Paleo channel) |
| Aircore (Hammer) | 85mm – 87mm | 120 m | 600CFM / 600PSI (Boosted) |
Will drill weathered horizon to 120 meters including Paleo channel, but faster in difficult drilling. |
| Slim Line RC | 95mm – 97mm Face Sampling RC Hammers |
100 m | 600CFM / 600PSI (Boosted) |
Will drill dry holes to 100 meters as fast as 4” RC, and “Wet” holes to approximately 80 meters |
Bostech drill rigs are extremely reliable. However, even the best machine at times can fail and to cover this eventuality Bostech Drilling Australia have in-house Mechanical and Engineering facilities. Combine this with an ongoing commitment to standardizing most components and you are ensured that spares can be readily produced at short notice, thus minimizing down time to the client.
Bostech Drilling rigs are designed and built in our Bellevue workshops. The design is based on many years field experience in the RAB / Air-Core drilling industry, with safety and operator comfort in mind.
The control levers are configured in such a fashion that minimizes the strain on the driller. The cyclone is configured to ensure no risk of injury when setting up/moving off holes. We have also developed a very effective mechanical splitter to reduce possible injury while sampling. The rigs are mounted on 13 tonne, and 18 tonne 4 x 4 trucks but can easily be adapted to fit on any carrier required.
Bostech Drilling Australia is always looking for solutions to industry-wide problems. One example is the use of hand-held stilton’s on drill rigs. Bostech Drilling has developed a new power wrench that negates the use for manual handling and many conventional alternatives and all the drawbacks associated with those systems.
With our extensive experience in desert regions, we have identified many problems associated with working in those conditions, especially tyre damage from staking. Bostech have developed, in conjunction with a well known Perth tyre manufacturer, a side wall protected super single tyre that allows for deflation over sandy surfaces while cutting down sidewall damage by 75% and improving vehicle flotation. After introduction, our tyre expenditure dropped to 30% from previous seasons drilled in the area.
Due to the fact that trained staff maintains our equipment to a very high standard, Bostech rig availability is up in the 96- 98% range. Considering the remote area and availability of mechanical help, our record is exceptional.
Our experienced crews are frequently able to drill an average of 600m Aircore and 800m RAB per shift. This consistently surpasses previous drilling company’s performance.
We continually innovate, using our own Engineering Division to provide safe and reliable equipment.
In tests conducted against other methods of Aircore systems, the Bostech system has proven to be superior, both in production and the ability to penetrate and sample difficult horizons. Bostech Drilling Australia has a long history of research and development and engineering solutions. Initially it was a pre-requisite for survival in a fledgling industry. Now it is an essential part of our company philosophy. We believe it gives Bostech a leading edge in safety and drilling performance.
