| METHOD | HOLESIZE | DEPTH | RIG AIR | COMMENTS |
|---|---|---|---|---|
| RAB | 3 7/8” – 4” | 120 metres | 600CFM / 250PSI | Will drill weathered horizon, ground conditions allowing, to 120 meters. |
| Aircore | 85mm – 87mm | 120 metres | 600CFM / 250PSI | Will drill weathered horizon to 120 meters (Including Palaeochannel) |
| Aircore (Hammer) | 85mm – 87mm | 120 metres | 600CFM / 600PSI (Boosted) |
Will drill weathered horizon to 120 meters including Palaeochannel, but faster in difficult drilling. |
| Slim Line RC | 95mm – 97mm Face Sampling RC Hammers |
100 metres | 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 have proved to be extremely reliable. However, even the best machine can fail, and to cover this eventuality, Bostech Drilling Australia have in-house Mechanical and Engineering facilities, which, combined with an ongoing commitment to standardising most components, ensures that spares can be readily produced at short notice, thus minimising 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. The Bostech Drilling rigs have been designed with safety and operator comfort in mind.
The control levers are configured in such a fashion that minimises reduces the strain on the driller. The cyclone is configured so that there is no risk of injury when settling up/moving off holes; also we have developed a very effective mechanical splitter to reduce possible injury while sampling.
The rigs are mounted on 13 tonne, 4 x 4 trucks; however they can easily be adapted to fit on any carrier required.
Bostech Drilling Australia are 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 and held and conventional alternatives and 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 maintain 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 Air-core 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 Air-Core systems, the Bostech system has proven to be superior, both in production, and the ability to penetrate and sample difficult horizons.
