Summary The paper looks into a situation typical for the Verkhnekamskoe potash deposit. When performing vertical seismic profiling, refractions are recorded that are formed on a rigid acoustic boundary separating terrigenous rocks from a high-velocity salt stratum. The properties and regularities of refractions propagation during vertical seismic profiling are described. A technique for summing refractions is proposed for constructing a supergather that allows tracing and obtaining quantitative estimates of near vertical fractured zones. Combination of the proposed technique and seismic tomography expands the possibilities of borehole seismic geological interpretation.

Summary The results of research on the development of a wave field model obtained during the study of frozen rock mass with crack by GPR are presented. The presence of cracks significantly affects the physical and mechanical properties of rocks, which must be taken into account when planning mining operations and the construction of mining facilities. To establish the peculiarities of manifestation of cracks in the GPR data studied materials of long-term fieldwork in developing areas of alluvial diamond deposits ("Almazy Anabara"), the basic building blocks of GPR and presented in single formula. This formula implemented in program in CKM Matlab, and the results of its performance are compared with simulation results in the system of gprMax. The comparison of the obtained results showed the identity of structure of the GPR wave fields. The correlation coefficient between the obtained matrices, without taking into account the low-amplitude values of multiple re-reflections was 0.91. The conducted studies confirmed the possibility of mathematical description of GPR wave field obtained by probing an array of frozen rocks with crack. The high correlation coefficient showed the adequacy of the developed model of radargram which will be finalized taking into account the radiation patterns of existing GPR.

Summary Recent climate change leads to local changes in the weather.

The development of a network of roads and railways in mountainous areas inevitably leads to an increase in the number of destructive natural impacts on transport infrastructure facilities. As a rule, the structural requirements for strength and durability, implemented during the construction of facilities, ensure the safe movement of vehicles. However, interruptions in traffic are periodically observed due to floods, undermining and destruction of bridges and other transport facilities. For example, the flood in October 2018 p. The tip has led to the collapse of the automobile bridge at the confluence of the river. Chicken in r. Tuapse, and traffic stops on the only straight road connecting Maykop and the Black Sea coast (Figure 1). In such conditions, ensuring the safety of vehicle traffic significantly depends on the ability to predict the onset of extreme natural anomalies, the volume and speed of the spillway on mountain rivers and the analysis of the possible destruction of culverts and water protection structures.

Summary Experimental research was carried out in order to improve diagnostics methods of roads operated in cryolitic zone. Results of ground-penetrating radar diagnostics at the Vilyui federal highway in Central Yakutia are presented. Data was obtained by OKO-2M GPR with AB-400 antenna unit (LogiS LLC). Attributes for interpretation of GPR wave fields are developed based on characteristics of GPR signals propagation in the road soils. Further it is used for mapping various cryogenic structures. For example, to identify water invasion zones at boundaries of the structural layers of the road surface and the roadbed, to determine zones of soil decompression at the subgrade support, to identify areas of swelling soils. As a result, GPR monitoring as part of engineering and geological survey allows reasonably plan and carry out actions to eliminate and prevent various types of subsidence and destruction of road surfaces, as well as to assess the nature and level of negative cryogenic processes.

Summary The article is devoted to the assessment of the possibilities of using geometric 3D inversions of electromagnetic time domain data measured by induction receivers moved using UAVs (UAV-TDEM). The electromagnetic field is excited by a long grounded electrical line, and the survey is carried out over profiles parallel to it. The geometric 3D inversion proposed for use was developed for processing airborne electrical survey data using helicopter platforms and is based on a joint search for electrophysical and geometric parameters of a geoelectric model using block structures. The study of geometric 3D inversion workability is carried out on synthetic data generated for a geoelectric model containing local targets at different depths overlapped by inhomogeneous conductive layer. Modeling is carried out taking into account the characteristics of the UAV system, obtained on the basis of analysis of practical data measured in one of the areas of Eastern Siberia. The results obtained showed that, on the one hand, the considered UAV-TDEM technology with a source in the form of a grounded electrical line makes it possible to detect local objects at depths of up to 100 m (and, possible, more) even in conditions of a heterogeneous and sufficiently conductive overburden layers. On the other hand, the considered approach to geometric 3D inversion makes it possible to stably determine the position in plan and the depth of local objects for the UAV-TDEM technology.

Summary A feature of inverted velocity sections is the presence of a low-thickness high-velocity surface layer (PVL). Such a layer can be formed by seasonally frozen and technogenically compacted soils, concrete and asphalt pavements [1, 6]. Observed on seismograms, observed according to the Y - Y observation scheme. Unlike normal sections, Love waves are not traced in inverse sections, since the conditions for their occurrence are not met. This circumstance allows us to identify useful reflected waves confined to the boundaries in the depth range from the first meters to the first hundreds of meters.

Summary Geophysical methods have recently been increasingly used in geoecological studies, including engineering and geological surveys and state monitoring of the shelf subsoil. The most widely used are various types of seismoacoustic profiling, side-scan sonar, multi-beam echo sounding. Seismoacoustic methods give an idea of the morphology of geological bodies and indirectly indicate their genesis and composition of the enclosing sediments. They are most widely used in the assessment of gaseous sediments and in the identification of gravitational processes. Side-scan sonar makes it possible to identify zones of ice scouring, to give the dimensions of relief mesoforms, as well as to estimate the intensity, type and direction of lithodynamic flows. Multi-beam echo sounding allows one to assess the morphlology of the seabed over large areas and to distinguish various genetic types of relief with their quantitative characteristics. The report provides numerous examples of the use of geophysical methods for solving various geoecological problems. It is concluded that for tasks such as determining the thickness and distribution of frozen rocks, geophysical methods at the present stage cannot give an unambiguous answer. The need to prepare a methodological manual on the use of geophysical methods for solving geoecological problems is indicated.

Summary Alexander Badanin worked in the research department of JSC NIPII Lenmetrogiprotrans from 2003 to 2019 as a senior researcher and his main activity was electrical exploration. During this time, he developed a non-standard methodology of electrotomographic observations, which was used both when working from the surface and in underground workings. A feature of this technique is a certain order of the supply and receiving groundings movement along the electrotomographic profile, which makes it possible to obtain an integral geoelectric section without using multi-electrode streamers and a large number of electrodes. This procedure allows to significantly reduce the time of field measurements and to quickly obtain 2D electrical tomography data for an initial assessment of geotechnical conditions and making a decision on the need to use more detailed methods of geophysics and geotechnics. Electrotomography according to this technique is a simplified version of the electrotomography (alternative electrotomography) and is distinguished by its mobility and less labor costs during field work. A clear advantage of the given express method in comparison with standard methods (using multichannel streamers) is large spacing, which allows, although roughly, but integral for a large rock mass, to estimate the distribution of electrical resistance in the section.
Alexander Badanin于2003年至2019年在JSC NIPII Lenmetrogiprotrans研究部工作，担任高级研究员，主要从事电勘探工作。在此期间，他开发了一种非标准的电层析观察方法，用于地面和地下工作。该技术的一个特点是供电和接收地沿电层析剖面有一定的运动顺序，这使得在不使用多电极拖缆和大量电极的情况下获得完整的地电剖面成为可能。该程序可以显著减少现场测量的时间，并快速获得二维电子层析成像数据，用于岩土条件的初步评估，并决定是否需要使用更详细的地球物理和岩土技术方法。根据该技术，电断层扫描是电断层扫描(替代电断层扫描)的简化版本，其特点是在现场工作中具有移动性和更少的人工成本。与标准方法(使用多通道拖缆)相比，该方法的一个明显优势是间距大，这使得虽然粗略，但对于大型岩体来说，可以估计剖面中的电阻分布。

Summary The result of research shows the possibility of complex geological and geophysical research for structural mapping of ore-promising areas and detailed study of ore control complexes of copper bearing sandstones in the Zhezkazgan region in Central Kazakhstan. The structural and tectonic structure of ore districts has been studied; The localization and morphology of differentiated intrusive arrays at depth has been established; Deep ore-controlling faults have been detected and mapped, ore control structures have been isolated in sedimentary and effusive sedimentary folding complexes; defined the spatial position of individual ore zones. Considering the complicated geological structure of the ore region under study and the significant differentiation of the formation and ores, the identification of additional criteria for the localization of copper ore is possible only with the combination of geological and geophysical methods, detailed geochemical and physical-chemical studies of rocks and ores.
