When mining potash with boring and continuous mining machines the operator may have a limited view in which he is making decisions about controlling the miner and the cutter. Geosteering began a collaboration effort with a Potash Mine to use the Rotar Gamma Detector's Gamma Assemblies.(ROGA) technology for the Potash mining application in 2003.


The operator sometimes needs assistance with Ore-Grade improvement due to limited visual visibility.


  • ROGA Gamma Detector is a very rugged, very compact design allows mounting on rotor, and highly integrated design produces superior performance.
  • Detectors guide the continuous mining boring machine to stay in the highest grade ore.
  • Elevation of cutter is adjusted to stay in potash seam.
  • Roll position is controlled by comparing seam position from multiple detectors.
  • Geosteering accomplishes the steering for solid mineral mining through direct measurements made on the formation in the region where cutting is performed.
  • Microcontrollers collect and organize date to correlate with rotor position.

The ROGA Interface Test Assembly (RITA) was developed by GMS to test the ROGA gamma detectors on the miner or in a lab environment.

RITA is used to verify the gamma detectors are functioning properly and to verify that the proper interfaces exist between the ROGA's and boring miners.
Data is output from the RITA through wireless links to a computer to allow evaluation of the system operations and to evaluate the radiation characteristics of formations that have been mined.
