Top of Coal Detection technology progressing towards commercialisation
PRESS RELEASE | 19 August 2020
Mining3 and CR Digital
are pleased to announce a partnership with the next phase of development in Top
of Coal technology. This announcement comes on the back of promising new
results delivered from the most recent Bowen Basin trial, where the technology
was tested over 12 weeks and collected downhole data from over 250+ boreholes.
Accurately detecting the approaching top of a coal seam prior to blasting is
fundamental to efficient coal recovery. During the extraction stage, a
significant percentage (up to 12%) of overall coal loss is attributable to
blast damage and coal dilution, which then makes it difficult to separate the
coal cleanly from the waste during both overburden excavation and coal
processing. By eliminating the damage done to the top of seam, substantial
increases in recovery are enabled.
With support from ACARP, Mining3 has been developing a measurement while
drilling (MWD) system that detects the top of a coal seam while routinely
drilling blast holes.
During the drilling process, the detection system uses resistance measurements
ahead of the drill bit to detect approaching coal in real-time. This method of
detecting Top of Coal brings significant benefits to surface mining operations,
- Providing a reliable indication
of the approach to Top of Coal that will enable drilling to be stopped
before touching coal or at a minimum standoff distance
- Increase production by reducing
damage to coal from blasting
- Strata recognition and mapping
during routine blast hole drilling
The system can also be retro fitted to a standard rotary air blast drill
CR Digital, a leading mining technology company, and part of the global CR
Group, is now working with Mining3 on the commercialisation of the technology,
and the integration of the Top of Coal technology into their technology
Together, Mining3 and CR Digital see potential for the technology to be an
extension to the Thunderbird 1110 and StrataSense products within the CR
Digital portfolio. Collectively, this agnostic range can be retro fitted
to any rotary air blast drill rig and is intended to build on the StrataSense
capability of CR Digital, to compile a three-dimensional understanding of the
bench and coal seam in real-time.
Mining3 and CR Digital thanks ACARP and its coal members for supporting the
most recent trial, we look forward to continuing to work closely to develop and
commercialise recent research findings.
