RIM (Radio Imaging
Method)
(see brochure...pdf)
Having a RIM™ survey
performed at your mine reduces mining
risk and ensures continuous and efficient ore extraction. In addition to
coal mining, RIM™ surveys can benefit metalliferous mining, environmental
research, and civil engineering. RIM™ surveys were first introduced in the
mid 1980s. Since then, we have performed more than 500 RIM™ surveys world
wide
Our equipment can be used in underground
entries, surface and underground boreholes, open-pit outcrops, heap leach
piles, and surface-to-underground configurations to produce large-scale
images of the geologic structures.
RIM™ does this by sending electromagnetic (EM)
waves through the subject area. The EM waves detect differences in
conductivity between subsurface features, which are used to produce images
of the geology’s electrical nature. Our geophysicist conducts the
analysis, presentations, and follow-up consultation to interpret those
images and tell you what lies hidden in your mine.
RIM-IV
has improved transmission range and enhanced resolution over the original
RIM™ configuration, along with increased receiver sensitivity and higher
imaging frequencies. It also is equipped with specialized tomographic
reconstruction software, which allows RIM-IV to provide state-of-the-art
three-dimensional images (3‑D RIM
In coal mines, RIM-IV is used to identify and
locate anomalies in the coal seams that could cause costly interruptions or
shut down mining completely. In metalifferous mining, RIM-IV aids in
resource evaluation and mine planning by better delineating the ore
structure and imaging host rock between boreholes. In all facets of mining
and civil engineering, RIM-IV provides superior void detection capabilities
to image natural and mine-related voids in the subsurface.
