From the Arctic to Australia, from coal mines to windfarms, energy developments to skyreaching superstructures, Robertson Geo technologies have been used to acquire quality geophysical data from over 160 countries around the globe.
Mineral explorers rely on a wide range of geophysical techniques including magnetic, gravity, electrical, electromagnetic and radiometric, and above all on strong knowledge of hardrock geology and on results of local field mapping and exploration drilling. By itself, no geophysical anomaly can simply be correlated with lithology (Lyatsky, 2004).

Geophysics at the ISGS is a Nearsurface Geophysics research program, focusing on methods and tools tailored to characterization of the upper 300 feet below land surface. Many of our methods and tools target much shallower depths, and applications in forensics and archeology are focused on characterizing materials and objects within the upper 310 feet below land surface.

The life cycle of mining begins with exploration, continues through production, and ends with closure and postmining land use. New technologies can benefit the mining industry and consumers in all stages of this life cycle. This report does not include downstream processing, such as smelting of ...
offers 1,038 mineral detection equipment products. About 13% of these are industrial metal detectors, 4% are testing equipment, and 1% are mine drilling rig. A wide variety of mineral detection equipment options are available to you, such as free samples.
Given the right geological setting, this makes it possible to selectively mine a coal seam; separating coals of varying BTU value and selling that coal at marginally higher prices; thus increasing the value of the deposit. Coal seams can also be evaluated insitu by geophysical .
Thus, to reduce mining costs it is essential to delineate the geology prior to mining. Today, the only effective geophysical tool to detect and to map minor faults in front of the coal cutter is inseam seismics using channel, or so called seam waves. The techniques are well established and successfully applied for more than two decades.
Coal mining, extraction of coal deposits from the surface of Earth and from underground. Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th
