Instruments Used In Dams

Although airborne geophysics have been conducted since the 1950s, in recent years, significant Technological breakthroughs in the instrumentation and methods have led to it becoming a critical tool in mineral exploration. Airborne surveys are widely accepted and promoted within the industry as being the first step in the exploration process.

Instrumentation In Dams Concept

Magnetic gradient surveys, electromagnetic surveys, radiometric surveys, gravimetric surveys and various other remote sensing methods are all now frequently carried out by aircraft. Most commonly the equipment is installed on specially customized fixed wing aircraft. However, there are also systems that can be towed by, or attached to the skid gear of helicopters, permitting even lower and slower data acquisition in terrain that is inaccessible to fixed wing aircraft. The future of geophysical surveys is bright as the methods continue to evolve and produce better results with airborne methods adding a new dimension of ease to the acquisition process.
