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.","PeriodicalId":486194,"journal":{"name":"Vestnik SGUGiT","volume":"30 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":"134980591","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}

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.","PeriodicalId":486194,"journal":{"name":"Vestnik SGUGiT","volume":"147 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":"134981261","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}

The high-degree model EIGEN-6C4 has a smaller standard deviation ( = 5,24 mGal) compared to other geopotential models.

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.","PeriodicalId":486194,"journal":{"name":"Vestnik SGUGiT","volume":"26 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":"135158181","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}

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}
