Boart Longyear launches new drilling orientation system

As the mining industry slows down and the focus is on slashing costs and creating efficiencies, new technological developments are being seen as the way forward.

With this in mind Boart Longyear has developed new integrated instrumentation for drillers to increase efficiency.

The company has created TruCore, a device which it claims is "a first-in-industry integrated core orientation system that enables drillers to increase productivity and decrease spend on consum­ables".

Core orientation is essential in the mining industry as it marks out and determines the precise orientation and position of core while in the ground.

This information helps drillers determine faults, cleav­ages, joints, mineral lineation, and any other ­geophysical properties of the site that can lead to better mapping for exploration and site development.

"While essential for mapping exploration and mine site development, core orientation is part of the drilling process that has only experienced incremental product improvements through small changes to the processes and equipment, until now," Boart Longyear global product manager Chris Lambert said.

"The innovation behind TruCore improves productivity and reduces the number of parts drill crews need to maintain a core orientation system which in turn reduces costs," he said.

One of the main differentiations of the system is that additional extensions are not needed when the integrated TruCore housing combined with Boart Longyear's outer tubes, reducing the number of joints and high wear on outer tube extension barrels.

This system's core marking technology now allows one tool to always be in the hole.

"The ability to send a second TruCore tool down immediately after the first tool is retrieved combined with wireless communication means core readings can be taken without having to break a joint in the inner tube, which leads to a faster drill site operation," Lambert said.

The design uses optical communication to send measurements to a hand-held control device allowing the drill string to stay assembled.

A pocket sized controller simultaneously controls the two core orientation instruments, increasing productivity by validating measurements while minimising errors.

Highly visible flashing LEDS aid direct alignment, reducing total tool measurement time.

Boart Longyear added TruCore comes in sizes BQ through to PQ.

It went on to state "TruCore is the first product in Boart Longyear's first ever line of instrumentation solutions, which will include TruShot and TruProbe, which are slated for late 2014 and 2015 respectively".
