      ABSTRACT

      Purpose.The paper analyzes a problem of surface deformation as a result of low-inclined seam underground mining in Paroseni mine, Romania. Solving this problem makes it possible to predict the effects of the underground mining on the surface while offering the possibility of taking appropriate measures to protect the objects already available in the area or those to be built.

      Methods. In order to analyze the behavior of the surface affected by underground mining of the coal seams in Paro-seni mine, the influence function method was applied.

      Findings. In the paper, the authors analyze how the underground mining acts on the surface in the case of the coal extraction in Paroseni mine, Jiu Valley, Romania. The possibility of important object placing in the area affected by the underground mining has also been analyzed.

      Originality. The paper is an original case study; the results, presented by the authors, have been obtained while using the influence function method, a well-known and widely applied method for investigating the subsidence phenomenon.

      Practical implications. The obtained results represent the prognosis of the surface deformation due to underground coal mining in Paroseni mine, Romania. These results were considered precise enough to determine the amount of surface deformation and the possibility of important object placing in the area affected by the extraction.

      Keywords: underground mining, prognosis, influence function, subsidence, horizontal displacement
