Geoelectric Discontinuity Detector
H. Trazaska · 1973
It is sometimes necessary to quickly localize a mine bed within an accuracy of a few cm. in depth. Such high accuracy measurements are made by chemical or physiochemical methods. These methods have the disadvantage of requiring a few hours of time due to the necessity of measuring the metallic content of the ore in the laboratory rather than in situ. Sometimes high accuracy in the measurement can be sacrificed in the interest of obtaining results more quickly.
