    • Computational model for evaluating the state of geomechanical systems during computing experiments 

      Fomychov, V; Pochepov, V; Fomychova, L; Lapko, V (National Mining University, 2017-03-30)
      Purpose. To create a model allowing integration of the diverse features identified for the rock massif behavior by differentiation of various theories and real phenomena into a single information-analytical flow. Methods. ...

    • Distant interaction of rock mass clusters around underground opening 

      Griniov, V; Zakharova, L; Diedich, I; Nazymko, V (National Mining University, 2017-06-30)
      Purpose. To experimentally prove the fact of distant interaction between rock clusters during the irreversible displacements of rock mass. Disintegration of the rock mass does not necessarily imply loss in underground ...

      Iordanov, Ihor; Buleha, Ihor; Bachurina, Yaroslava; Boichenko, Hennadii; Dovgal, Vitaliy; Kayun, Oleksiy; Kohtieva, Olha; Podkopayev, Yevgen (Dnipro University of Technology, 2021-12-30)
      Purpose. Substantiation of the conditions for haulage drifts stability using different protection methods in steeply dipping seams based on a set of experimental studies. Methods. To achieve the purpose set, mine ...

    • Neural simulation-based analysis of the well wall stability while productive seam penetrating 

      Katanov, Yuriy; Vaganov, Yuriy; Cheymetov, Matvey (Dnipro University of Technology, 2021-12-30)
      Purpose is the development of mathematical models to evaluate deformation of parameters of the rock mass-well geological and engineering system within the anisotropic media. Methods. Both mathematical and neural modeling ...

    • Numerical methods of geomechanics tasks solution during coal deposits’ development 

      Bondarenko, V; Hardygora, M; Symanovych, H; Sotskov, V; Snihur, V (National Mining University, 2016-09-30)
      Purpose. Generalization of numerical modeling of geomechanical processes in the vicinity of mine workings by finite elements method and making recommendations for substantiation of suitable construction and behavior of ...

    • Stability of the coal seam roof during the sudden collapse of lateral rocks 

      Podkopaiev, S; Iordanov, I; Chepiha, D (National Mining University, 2017-09-30)
      Purpose. To study the effect of dangerous manifestations of rock pressure (in the form of sudden lateral rock collapse) on the state of the coal seam roof developed in difficult mining and geological conditions by various ...
