If there is a previously mined out adjacent longwall next to the salvage chamber, the duration of salvage operations increases significantly, in contrast to the case when the salvage chamber is located within a pillar, outside the zone affected by the previously mined out longwall. In this regard, the calculation of the stress state of the pillar for the salvage chamber in the presence of an ad-jacent previously mined out longwall is a relevant task. The paper presents a methodology for quantitative assessment of the stress affecting the pillar for the salvage chamber, based on the use of the finite element method. An example of calculating the stress on the pillar for the sal-vage chamber in the presence of an adjacent mined out longwall for specific geological and mining conditions is considered. It has been established that the presence of a previously mined out adjacent longwall causes additional load on the specified pillar. The highest load factors are observed in the edge part of the pillar near the ventilation gateroad.","PeriodicalId":41869,"journal":{"name":"Proceedings of the Tula States University-Sciences of Earth","volume":"421 1","pages":""},"PeriodicalIF":0.1,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70573914","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}
