PROCEDURE FOR RESONANCE-RAPID SEISMIC PROSPECTING Russian patent published in 2011 - IPC G01N1/00 

FIELD: machine building.

SUBSTANCE: excitation and record are performed in one common point. Excitation is carried out with an impact of limited force sufficient for initial excitation of collective synchronous oscillation of atoms in lattice sites of minerals in composition of soils (rock) at frequency at least 25 000 Hz. Starting from the moment of excitation there are continuously and in time measured and recorded frequency of initial excitation of atom oscillation, system-changing to value of 0.1 Hz, and changing energy of descending frequency of initial excitation of atoms. On results of measured data processing there are allocated values of frequencies with amplitudes reflecting presence of structural (real) or other boundaries in massif of rock, interesting for analysis, time of changes of initial frequency of excitation to values of allocated frequencies, time of change (descending) of any allocated frequency to frequency determined with detail of analysis, and time of attenuation of fluctuations of rock massif within the range of frequencies or on separate frequency interesting for analysis. Using obtained quantitative and qualitative data, and generally accepted or specific, established by calculation and (or) experimentally analytic dependencies there is determined depth of selection of structural and (or) other boundaries of geological and (or) other objects. Vertical time-distance curve is plotted in each (or chosen) point of profile to required depth. There is determined velocity of fluctuation propagation, and physic, physic-mechanical, and geo-mechanical properties of massif of soil (rock).

EFFECT: increased resolving capacity and reliability of selection of structural elements in massif of rock, upgraded accuracy in determination of velocity characteristics of analysed massif of rock with complicated structure; raised validity and information value of observation results.
