PROPAGATION OF VLF WAVES. VLF MEASUREMENTS IN THE MINE OF BLEIBERG.

Abstract

Measurements of VLF propagation in rock showing considerable mineralization (ZnS, PbS) are described. The measurements show that inhomogeneities can be proved with satisfactory accuracy only by choosing the frequency and distance of measurement adequately. Besides these measurements conducted by means of a VLF transmitter set up in the mine, the reception of VLF transmitters (GBR) over large distances was measured and the results are discussed.
