Abstract The article discusses a numerical model for assessing the depth for the passive method of induced polarization based on previously obtained experimental data at the Samson field (Republic of Khakassia). The model is based on the mathematical model of Komarov, who derived equations for the anomalous polarizability of a sphere observed on the Earth’s day surface, the proposed model for estimating the depth of the anomaly depends on the size of the proposed field and the induced polarization coefficient observed on the surface. In the course of the numerical assessment, it was shown that there is a convergence of data from field observations, exploration drilling and mathematical modeling.

Abstract When determining the causes of structural defects of a steel rope, the technology of carrying out work on splicing by a team of specialists was studied in detail. Field observations and experimental studies, as well as mathematical modeling of the process of structural defects formation in the rope joint section, allowed to establish that the cause is the imperfection of the existing technology for performing splice work [1-5]. The existing technology directly depends on the experience (professionalism) of a splicing team and provides for the work on splicing, as a solution to a new problem for every hawser, expressed in the design and calculation of the main parameters, according to the established standards of the rope manufacturer. It is noted that this labor function negatively affects a person, causing dangerous and harmful factors of the working environment, such as: severity and intensity of the labor process. Under the influence of dangerous and harmful factors, the specialist is subject to: static and dynamic overload, mental overstrain, neuropsychiatric overload, which negatively affect a person and, as a result, affect the quality of the work performed as a whole. The total accumulation of dangerous factors in the course of work leads to the decrease in the quality of the obtained results and deviation from the normalized indicators, which is unacceptable and leads to the formation of structural defects of a steel rope.
