Over time, these large excavations have lost their stability (collapse of the mines to the surface and various degrees of instability of the Carol and Mihai mines), keeping only the Unirea mine in operation for tourist purposes. This article is a synthesis of the analysis with 3D finite elements, in elasto-plasticity, of the state of stress and strain developed around the excavations and highlighting the factors that led to the loss of their stability, focusing on the Unirea mine.\n                  <\/jats:p>","DOI":"10.2478\/minrv-2021-0002","type":"journal-article","created":{"date-parts":[[2021,4,15]],"date-time":"2021-04-15T11:14:59Z","timestamp":1618485299000},"page":"12-23","source":"Crossref","is-referenced-by-count":2,"title":["Finite Element Modelling of the Stability of Underground Mining Excavations at Old Mines \u2013 Sl\u0103nic Salt Mine"],"prefix":"10.2478","volume":"27","author":[{"given":"Dacian-Paul","family":"Marian","sequence":"first","affiliation":[{"name":"University of Petro\u0219ani , Petro\u0219ani , Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ilie","family":"Onica","sequence":"additional","affiliation":[{"name":"University of Petro\u0219ani , Petro\u0219ani , Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"374","published-online":{"date-parts":[[2021,4,13]]},"reference":[{"key":"2026042820593676128_j_minrv-2021-0002_ref_001","unstructured":"[1] Hirian, C., 1981 Rock mechanics (in Romanian), Didactic and Pedagogic Publishing House, Bucharest"},{"key":"2026042820593676128_j_minrv-2021-0002_ref_002","unstructured":"[2] Hirian, C., Georgescu, M., 2012 Stability of the old Salt Mines from Romania \u2013 condition of their use for various fields (in Romanian)., Universitas Publishing House, 2nd edition"},{"key":"2026042820593676128_j_minrv-2021-0002_ref_003","unstructured":"[3] Milea, M. et. al., 2009 Study of the physical-mechanical and rheological parameters of the rock salt from the Sl\u0103nic Prahova deposit and resizing the elements of the resistance structures (pillars-ceilings) of the extracted areas (Cantacuzino mine), in order to ensure the overall stability of the area, Stage II \/ Part 1 - Statistical processing of the data resulting from laboratory tests (in Romanian)., SC MINESA-ICPM SA Cluj-Napoca, Research Contract no. 10 848\/2011\/26.10.2007; Symbol project 49-724-01"},{"key":"2026042820593676128_j_minrv-2021-0002_ref_004","unstructured":"[4] Stamatiu, M., 1959 The problem of pillars design at rock salt mines in Romania (in Romanian)., Publishing House of the Academy"},{"key":"2026042820593676128_j_minrv-2021-0002_ref_005","unstructured":"[5] Stamatiu, M., 1962 Rock mechanics (in Romanian), Didactic and Pedagogical Publishing House, Bucharest"},{"key":"2026042820593676128_j_minrv-2021-0002_ref_006","unstructured":"[6] Marian, D.P, Onica, I., Georgescu, M., Cozma, E. et.al., 2019 Study on the stability of constructions and surface in the perimeter of influence of Old Mines (Ocna din Deal and Ocna din Vale), Victoria, Unirea and Cantacuzino according to know existing data (topographic, rheological, geological, hydrogeological, etc.) as well as the deformations of the resistance elements of the underground excavations in the Cantacuzino mine, in order to carry out in safe conditions the underground mining activity and protection of the civil and industrial (in Romanian), University of Petrosani, Research Contract no. 186\/15.10.2019"},{"key":"2026042820593676128_j_minrv-2021-0002_ref_007","unstructured":"[7] Onica, I., Marian, D.P., 2016 Applications of the finite element method in the analysis of surface stability and underground structures (in Romanian), Universitas Publishing House, Petrosani"},{"key":"2026042820593676128_j_minrv-2021-0002_ref_008","unstructured":"[8] Berchimi\u015f, S. et. al., 2004 Identification of fractures and fissures in the Cantacuzino and Unirea Mine by geophysical methods; Stage I \u2013 Cantacuzino Mine, Levels VIII, IX, X (in Romanian), SC IPROMIN SA, Research Contract no. 16079\/2004"},{"key":"2026042820593676128_j_minrv-2021-0002_ref_009","unstructured":"[9] Oancea, I. et. al., 2006 Monitoring the mining subsidence in salt mines by geophysical tomography methods in order to avoid collapse phenomena.
