Iron Ore | Setting a new benchmark for RC drilling

Since 2003, Wallis Drilling has operated in over 20 iron ore sites across the Pilbara and Africa. Currently, Wallis completes over 300 kilometres of RC drilling a year.

Our major clients tell us that we have set a new benchmark for drilling contractors working for their organisations.

Our reputation is the result of attentive contract management, professional supervision, extensive mechanical support and an innovative approach to constantly improving equipment, work systems – and by always adding value to our services.

Standardisation of these drill rigs ensure the operation and management of these drilling contracts are efficient and safe.

Our 50 years of drilling experience means we can get the job done efficiently and safely with the very minimum of downtime. We pride ourselves on our ability to be cost-efficient and deliver on our client’s targets.

How we do it

Our first work in the iron ore industry was in 2003 with a multi-purpose machine carrying out RC infill drilling in the Pilbara.

We now have ten Schramm T685WS RC machines mounted on all-wheel drive trucks. Each rig is supported by MAN all-wheel drive support, auxiliary air and water truck.

The rigs are equipped with the latest safety features including automated rod handling, interlocked rotation guards, dust suppression systems, as well as both mine and UHF radio communications. The full range of safety features is listed in our ‘Range of RC Drilling Rigs’.

All crew vehicles have satellite tracking systems so that movements can be monitored.

Innovative solutions to difficult problems

Drilling in the Pilbara brings unique problems and challenges.

Some projects have involved drilling 350 metre-deep holes in valleys with excessive groundwater. The other extreme has been hill work in areas where the slope reached 26 degrees.

We have encountered conditions such as above and below water table ore bodies, and the variety of mineralisation present across the Pilbara is a constant challenge. Some areas have proved routine where others have required a high level of technical experience. These situations have given our drilling crews the expertise to handle challenging situations where traditional RC techniques are ineffective.

We have developed a system where we can retrieve drill pipe that has become bogged in difficult ground conditions. This method allows us to successfully retrieve 95% of all drill pipe that has become bogged

This represents a large cost saving to our clients as claims for lost equipment have been significantly reduced.
