BIM technologies include: 3d design, information modeling (IM) of existing objects and process control. When creating a BIM model, as a rule, information about aboveground structures is used, less often aboveground and underground objects, and in some cases aboveground, underground objects and a geological 3d model. The close integration of BIM into the industry has a positive effect at all stages ofproject implementation, which is expressed in reducing the time, cost and improving the overall quality of work. Such a trend leads to an increase in the number of software products that support activities in the BIM environment, which, however, may cause the problem of choosing the most optimal software that meets all the needs of the user within his professional tasks. In the Russian market, geologists and designers use a fairly large number of programs for building volumetric engineering and geological models and transmitting this information to the project. Most of the programs used are quite time-consuming and have a high cost. In the article the existing programs on the market are considered and the choice of the most effective for creating BIM-models is made.","PeriodicalId":41869,"journal":{"name":"Proceedings of the Tula States University-Sciences of Earth","volume":"1 1","pages":""},"PeriodicalIF":0.1,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70575014","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 article proposes a technology using a scraper with combined equipment. The preparation of the kimberlite array for excavation is carried out when the scraper moves at idle speed by loosening the upper layer with simultaneous supply of natural brine through the teeth of the ripper into the underlying layer for its subsequent softening. After the scraper is turned, the loosened rock mass is excavated with an elongated bucket and transported to the transfer point.","PeriodicalId":41869,"journal":{"name":"Proceedings of the Tula States University-Sciences of Earth","volume":"1 1","pages":""},"PeriodicalIF":0.1,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70575269","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}

Analytical relations are given for determining the pressures at the front of the air waves of contact explosions and equivalent buried charges, depending on the mass of the instantly exploding charge and the distance to the protected object. An amendment is proposed that takes into account the simultaneity and imposition of the arrival of disturbances to the protected object from instantly exploding sites in various blocks at different distances during cascade explosions in open-pit mining. The dependences of the reduced depths of borehole charges operating on two free surfaces are presented. For operational calculations of UVV safety, a nomogram is presented on aligned parallel scales.","PeriodicalId":41869,"journal":{"name":"Proceedings of the Tula States University-Sciences of Earth","volume":"1 1","pages":""},"PeriodicalIF":0.1,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70575597","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}
