Through the exploitation of buildings, we witness changes in the geomechanical characteristics of the soil as a result of secondary influences characterized by climate change, the presence of sanitary and storm water, vibrations in urban areas and earthquakes. All the mentioned occurrences result in the settlement of bearing parts, and thus endanger the structural parts of buildings. In the world of geotechnics, for the past few years we have witnessed the affirmation of the Deep Injections method, which is used for rehabilitation, but also for improving the foundation soil of existing buildings using expandable resins.","PeriodicalId":203089,"journal":{"name":"ZBORNIK RADOVA GEO-EXPO 2022","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122613679","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 landslides complicate open pit mine operations, but also pose a danger to individual objects, structures and related infrastructure. Those were the reasons which resulted in the need to perform detailed monitoring of landslides, to register changes in active processes, to establish databases and update, improve and recondition the processes themselves. Three landslides have been located within „Bogutovo Selo and Ugljevik East 1” open pit coal mines. The results obtained from hydrogeological and geomechanical surveys, as well as the data obtained from landslide monitoring, enable us to adequately restore objects, structures, related infrastructure and to stabilize the terrain itself at the open pit coal mine.","PeriodicalId":203089,"journal":{"name":"ZBORNIK RADOVA GEO-EXPO 2022","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128197983","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 mining underground room GIN-200 is the main incline of the new part of the underground mine \"Rudnik\" and it is made from the surface in the length of 1100 m. According to its purpose it should be functional for a longer period of time. The project solution of support provided the certain methods of supporting according to the working environment, which is presented uniformly. Already in the early phase of this underground room construction, it was determined that these are on interchangeable conditions with cracked and weakened rock mass, and that a certain method of support was chosen, which is applied in practice. This paper presents the solution of the support of the this underground room with a special presentation of specifics and represents a contribution to the mining profession.","PeriodicalId":203089,"journal":{"name":"ZBORNIK RADOVA GEO-EXPO 2022","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122914757","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}
