A New Complex Near-surface Electromagnetic and Seismic Technique for 3-d Research of Inhomogeneous and unstationary medium

摘要

The monitoring results of geological medium show it's unstationarity. The causes of unstationarity displaying are united, so the registration of seismic and electromagnetic fields must be developed in the frame of united squared observation systme or the most definition of influence factors in the frame of existing equivalence. The idea of such observation systems construction is supported by the conception on three-staged interpretation of electromagnetic and seismic fields (in the dynamical variant). The developed new squared observation systems are oriented on the use of local exciting sources with united geometrical field structure: electromagnetic field-vertical magnetic dipole, seismic field - vertical exciting with a local strength Such observation system together with an original 3-D interpretation complex had been used for solution many geological problems, because of their flexibility and simple realization: by research of dynamics of season and ancient frozen ground zones by frosty and melting; by volume mapping of discrepancy and filtration zones and research of it's dynamics. That complex showed itself as an informational and technological device for monitoring the nature-technogenic processes in geological medium.
