Evaluation of rock mass fracturing based on electrical resistivity imaging models

(Ryazantsev P.A. )

The article considers possibilities of electrical resistivity imaging when evaluating fracturing. The correlation between resistivity and fracturing is investigated. The criteria of cracks different types localization and typical search image are determined on the basis of numerical simulations. The practical usefulness of achieved results is presented in the example of geophysical survey of facing stone deposit.......

Integrated geophysical studies to determine the location and the causes of deformations of the railway embankment

(Kapustin V.V. Fomenko N.E. Gaponov D.A. )

The implementation example of some modern geophysical methods: VES, EPTS, MG, SP, and RFM, in the studies of destructive zones in the place of drawdown subgrade in the area of the Gorky Railway have been presented in this paper. The results of step-by-step multi-level analysis of field work observations have been shown, which enable to decode the areas of variability of morphology, lithological characteristics and water saturation of ground layers.......

Geological and geophysical characteristics of deep geostructures of European plate

(Ogadzhanov V.A. Ogadzhanov A.V. )

The research of forming and conducted physics- geological modeling tectonic structures dilatаton genesis. It is shown that in the forming of dilatation tectonic structures of European plates determine an important processes penetration of fluids inward of rocs, including those associated with the processes of hydrocarbon generation. Geological-geophysical characteristics of the main types the dilatation structures of the European plate are defined.......

The structure and morphology non-tidal variations of gravity

(Antonov Yu.V. )

In the article the monitoring measurements of gravity in Bishkek (Kyrgyzstan) was analyzed. The observed tidal variations of gravity differ from the theoretical values of the attraction of the Moon and Sun. The difference between the measured and theoretical values of gravity is non-tidal variations of gravity. Obviously, the source non-tidal variations are the coronal mass ejection (CME) by the sun. The assumption was made that no tidal variations of gravity depend on solar activity. Source non-tidal variations can serve as the coronal mass emissions by the sun. The propositions about the influence of the terrestrial and cosmic processes in education non-tidal variations of gravity. This could serve as a criterion of short-term earthquake prediction.......

The spectral analysis of data of microseismic sounding

(Davydov V.A. )

Set of factors influencing a registered seismic signal and ways of allocation geological environment response is considered. Possibility of sounding on the basis of studying of spectral ratios vertical and horizontal microseismic displacements is proved. Examples of application microseismic sounding on some geological objects are presented.......
