The article discusses the development of methods for assessing mineral losses in the development of alluvial gold deposits as well as the optimization and reduction of their quantity. It is proposed to improve the quality of loss accounting by introducing a system of automated determination of the position of equipment during the development of the deposit. Statistical processing of the experimental data of the bulldozer positioning accuracy with the use of GNSS systems was carried out in the course of the research. Spatial positioning accuracy of the bulldozer blade was determined and was tested the hypothesis of subjecting the positioning errors to the normal law of distribution. Based on the results obtained a model of potential losses depending on the bulldozer's levelling and the thickness of the «protective jacket» - the unexcavated waste rock left over the expected boundary of the productive layer's roof was derived. Based on the generated model of losses, dependencies were derived to optimize the value of the "protective jacket" from the position of minimizing losses relative to the amount of potential gold losses and additional costs of transportation and flushing of waste rock.

To ensure the required accuracy of elevation and angle measurements, measures are taken at the station to rectification or significant reduce of the influence of the main instrumental errors. With regard to leveling, main errors are the violation of the main condition of the level (the influence of the constant component of the angle i), as well as the incorrect course (oscillations) of the spotting scope focusing lens when it is refocused (the variable component of the angle i). In this regard, in order to significantly reduce their influence, leveling at the station is carried out by the middle with an acceptable shoulder difference. The influence and magnitude of the focusing lens travel on the measurement, as well as methods for reducing the errors, are well covered for instruments with visual reading. With regard to the spotting scope of digital levels, which have different design and shorter focal length, the nature and magnitude of this influence is not covered enough. This circumstance is important when performing measurements with the instruments in terms of the possible expansion of technological tolerances for the inequality of the shoulders at the leveling station when performing geometric leveling.Therefore, the purpose of this research is to determine the nature and magnitude of stroke of the focusing lens of digital levels and, taking into account its influence, to make recommendations to existing measurement methods. To solve this problem, a verification technique was implemented by leveling the excesses from two stations. Studies have established that in high-precision digital levels, the amount of stroke of the focusing lens does not exceed 0.14 mm. This allows, when performing high-precision leveling, to increase the inequality of the shoulders at the station with virtually no loss of measurement accuracy.

The improvement of the gravimetric knowledge of the Russian Federation and the creation of new models of the Earth's gravitational field (EGF) in the form of spherical harmonics of the geopotential set the task of choosing the most suitable model based on the characteristics of the gravitational field on the territory of Russia. The satellite gravity missions CHAMP, GRACE and GOCE provide a homoge-neous and almost complete global coverage of information about the Earth's gravitational field. The paper presents the results of a study of the accuracy of modern high-degree global geopotential models for determining various characteristics of the Earth's gravitational field on the territory of the Russian Federation. The models EGM2008, EIGEN-6C4, GECO, SGG-UGM-1, SGG-UGM-2 and XGM2019 were used as the tested geopotential models. The results of the study are presented in the form of statistical parameters and histograms of the distribution of differences g between the gravity values obtained from ground-based gravimetric measurements and calculated from model data. The high-degree model EIGEN-6C4 has a smaller standard deviation ( = 5,24 mGal) compared to other geopotential models. Based on the distribution of differences, we can conclude that the EIGEN 6C4 model is the most suitable for the territory of the Russian Federation.

The closure of the Semipalatinsk nuclear test site (SNTS) and the introduction of its lands into the national economic circulation makes it possible to carry out various economic activities on its territory. Such activity also includes the development of the Karazhyra coal deposit located on its territory. During the nuclear tests, technogenic radionuclides contaminated the upper soil layer of this deposit, as well as groundwater. Currently, during overburden operations and subsequent coal mining, intensive dust formation occurs, which leads to secondary pollution by wind transfer of technogenic radionuclides, which leads to an expansion of the polluted area over the territory adjacent to the landfill. At the same time, the direction of transfer largely depends on the wind rose, which changes throughout the year. The transfer of radionuclides also occurs when contaminated coal is transported by road to Semey to industrial enterprises, as well as to the population of private houses. To ensure monitoring of the development of secondary pollution of this deposit and the territory adjacent to the landfill, it is necessary, in order to safely conduct economic activities, in particular cadastral activities, to display the level of pollution and the dynamics of its expansion on boundary plans. In this regard, consideration of this issue is relevant and timely. The article indicates the types of work that have an impact on the radiation situation of the environment, including on the lands adjacent to the Karazhyr coal mine. It has been established that the method of performing geodetic and cadastral work will be influenced by the level of territory contamination with technogenic radio nuclides. To display the level of pollution at different horizons, a method for creating a three-dimensional map of the deposit and a part of the territory adjacent to it is proposed.

Geodetic support of cadastral registration in Russia was a rather laborious task until recently associated with the need to perform measurements with inefficient tools, a significant amount of calculations and the formation of databases in the absence of specialized software and other reasons. In the unified state register of real estate (EGRN), today there are still errors that significantly complicate the process of forming new plots and lead to legal disputes between their owners. Therefore, many works of domestic and foreign researchers are devoted to the problem of detecting and eliminating such errors. However, when solving practical problems, there may be cases where legal disputes are caused by the content in the EGRN of many errors of various nature, leading to the seeming impossibility of establishing the truth in litigation. The article shows an example of such a problem and outlines methods to ensure its solution.

The article is devoted to the study of the identification of deviations of unmanned aerial vehicles from overlapping images of the underlying surface without determining the parameters of their mutual orientation. For this purpose, a mathematical model has been developed that establishes a functional relationship between the parallax differences of overlapping images and the deviation parameters of unmanned aerial vehicles. In this case, all possible types of deviations and options for their combinations are taken into account. Studies have been carried out and estimates of the influence of deviations on the magnitude of the change in the parallaxes of overlapping images have been obtained. The results obtained allowed us to conclude that during the flight of unmanned aerial vehicles it is possible to automatically identify and evaluate their allowable deviations from a given trajectory using the parallaxes of overlapping images without determining the parameters of their mutual orientation.

The article provides a comparative analysis of the results of calculating vegetation indices based on remote sensing data from various survey systems in order to determine the suitability of using Sentinel-2B satellite images to assess the degree of damage to natural components affected by oil spills. As the main criteria for assessing the informative capacity of remote sensing data, their spectral and spatial resolution are considered. The results of experimental studies characterizing the spatial distribution of the values of the NDVI and SAVI vegetation indices in the oil spill area are presented, on the basis of which the advantages and disadvantages of the Landsat and PlanetScope survey systems are determined when monitoring the state of open soils, including those contaminated with oil products. In order to increase the reliability of the results of the study, it is proposed to use modifications of the considered vegetation indices.

Recent advances in remote sensing technology make it possible to digitize the real world almost automatically. Airborne laser scan results are georeferenced data type. They provide detailed 3D information about objects and the environment. Automated classification and detection of objects obtained from lidar is necessary to minimize production costs. Although the optimization of traditional methods using rule-based algorithms has expanded geospatial applications, significant manual editing is still required to obtain a high quality data set. Unlike images, point arrays are unstructured, sparse, and have a non-standard data format. This creates a lot of challenges, but it also provides a huge opportunity to capture the details of scanned surfaces with millimeter accuracy. Classifying and separating non-ground points from ground points greatly reduces the amount of data required for consistent surface analysis, saving time and simplifying further analysis. The main idea of scientific research is to use deep learning as a section of machine learning to analyze an array of points. The paper presents a feature-based algorithm that classifies ground and non-ground points in airborne laser scanning cloud.

Airborne laser scan results are georeferenced data type. They provide detailed 3D information about objects and the environment. Automated classification and detection of objects obtained from lidar is necessary to minimize production costs. Although the optimization of traditional methods using rule-based algorithms has expanded geospatial applications, significant manual editing is still required to obtain a high quality data set. Unlike images, point arrays are unstructured, sparse, and have a non-standard data format. This creates a lot of challenges, but it also provides a huge opportunity to capture the details of scanned surfaces with millimeter accuracy. Classifying and separating non-ground points from ground points greatly reduces the amount of data required for consistent surface analysis, saving time and simplifying further analysis. The main idea of scientific research is to use deep learning as a section of machine learning to analyze an array of points. The paper presents a feature-based algorithm that classifies ground and non-ground points in airborne laser scanning cloud.","PeriodicalId":486194,"journal":{"name":"Vestnik SGUGiT","volume":"305 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134980750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
