BROADBAND SIGNAL RECORDER WITH REFERENCE TO SPACE-TIME COORDINATES FOR ELECTRICAL EXPLORATION GEOPHYSICAL WORKS

(STEF92 Technology, 2021-12-20, Vadim Zhmud, V. M. Semibalamut, Yury D. Fomin, Л. Дімітров, Denis O. Tereshkin, Oleg V. Stukach)

The paper solves the problem of creating a device for electrical measurements for the purpose of geological research. There are a large number of data acquisition and processing systems, analog-to-digital converters (ADC) and other serial processing technical means for measuring and storing analog electrical data with their preliminary conversion into digital readings. This is done for the purpose of subsequent processing of these signals, which allows calculating some characteristics, which are then used to calcu...

RESEARCH OF THE FEATURES OF THE DEFORMATION PROCESS IN THE BAIKAL REGION

(STEF92 Technology, 2020-09-20, Vadim Zhmud, Sergei Panov, Л. Дімітров, Yury D. Fomin)

Show more

The report presents the results of studies of the characteristics of the deformation signal during the preparation of regional earthquakes according to laser deformation measurements in the adit of the Talaya seismic station (Baikal region). Studies have shown a number of features during the deformation process on the eve of regional earthquakes. The deformation data recorded on the seismic station (? = 51°40`48``N, ? = 103°38`24``E) during the period from 1994 to 2015 were used as experimental material. During th...

SIGMA-DELTA PHASE LOCKING LOOP FOR GEOPHYSICAL RESEARCH

(STEF92 Technology, 2020-09-20, Vadim Zhmud, Yury D. Fomin, Л. Дімітров, Sergei Panov, V. M. Semibalamut)

Continuous measurements of deformations of the Earth's crust make it possible to record changes in their character in several characteristic parameters. Such parameters include the amplitude, phase, and frequency of periodic oscillations, for each characteristic frequency separately, as well as random typical or atypical artifacts. All this information with proper processing can be used for various purposes, one of the most important tasks in this case is to reliably identify earthquake precursors. These studies r...

COMPLEX ANALYSIS OF THE SIGNAL OF THE EARTH-S CRUST STRAIN METER IN THE BAIKAL RIFT ZONE

(STEF92 Technology, 2019-06-20, Vadim Zhmud)

Show more

From 1994 to the present, records of deformations of the Earth?s crust, which are measured by a laser displacement meter, called ?deformograph?, are regularly recorded. This meter records changes in the distance between the mirrors fixed on the rock inside the mountain gallery in two directions: North-South and West-East. Such observations are carried out in the Gorny Altai region, in Kazakhstan and near Lake Baikal. One of the long-acting deformographs is installed in the gallery of the Talaya seismic station in ...

SOFTWARE FOR PROCESSING AND VISUALIZATION OF MEASUREMENTS OF THE DEFORMATION OF THE EARTH'S CRUST

(STEF92 Technology, 2019-06-20, Vadim Zhmud)

Show more

Regular measurement of rock deformation processes makes it possible to make judgments about the nature of the deformations of the Earth's crust, as well as the likely precursors of earthquakes near the area where these data are obtained. Therefore, the continuous operation of measuring devices that record such deformations is extremely important. When measuring by laser methods in a normal atmosphere, the distance of measurements can be significant, up to 25 meters and higher. The disadvantage of such measurements...

HETERODYNE SIGNAL FILTERING FOR LASER MEASURING SYSTEMS

(STEF92 Technology, 2018-06-20, Vadim Zhmud)

Show more

Laser systems are widely used for measuring the most important physical values with the highest accuracy. In particular, laser measuring systems are used to identify earthquake precursors in monitoring tidal rock fluctuations. In many cases, signals from laser measuring systems contain noises that need to be filtered out. The signal component in this case has the form of a harmonic oscillation, the frequency and phase of which change and these changes carry information about the measured quantity. This signal shou...

THE PHASE LOCKING SYSTEM FOR THE FREQUENCY LOCKING OF LASERS FOR GEOINFORMATICS

(STEF92 Technology, 2018-06-20, Vadim Zhmud)

Show more

Lasers are the most accurate measure of distance increment. Therefore, they are used to detect ultra-small oscillations of rock under the influence of tidal forces [1?6]. This allows identifying the accumulated tensions in the earth's crust. The change in the type of such fluctuations indicates the possibility of earthquakes in the near future, which allows reducing the damage from such catastrophic events, to save the lives of many people. Currently, such systems use frequency locking of two or more lasers to eac...

MODIFICATION OF OPTOELECTRONIC INTELLECTUAL SYSTEMS FOR ABSOLUTE MEASUREMENTS IN MONITORING OF EARTH SEISMIC DYNAMICS

(STEF92 Technology, 2017-06-20, Vadim Zhmud, Vladimir Semibalamut, Lubomir Dimitrov, Aleksey Taichenachev)

Show more

Predictions of catastrophic seismic events are extremely important. Such predictions are based on the continuous monitoring of many varying values characterizing the tension in the earth's crust. One of these indicators is micro oscillations in the Earth's crust, committed under the influence of the lunar-solar tidal forces. Devices for the registration of these oscillations are extremely complex, based on laser interferometric techniques. These devices converts length increment into according increment the phase ...

THE INCREASE OF THE ACCURACY OF THE LASER-BASED MEASUREMENT OF ULTRA-LOW TIDAL DEFORMATION OF ROCKS

(STEF92 Technology, 2017-06-20, Vadim Zhmud, Vladimir Semibalamut, Lubomir Dimitrov, Yury Fomin)

Show more

The laser meter of super small rock displacement under the influence of gravitational forces from the moon and the sun allows registering the regular fluctuations in the Earth's crust. These fluctuations provide small difference in the distances between the rocks edges in the two orthogonal directions inside the shaft structure drilled in the rock. Laser-based displacement meter converts the distance change into the increment of the phase difference in the two light beams in the interferometer. The photo detector ...
