    • Analyzing kinetics of deformation of boundary rocks of mine workings 

      Nehrii, S; Sakhno, S; Sakhno, I; Nehrii, T (National Mining University, 2018-12-30)
      Purpose is to analyze nature of rock deformation and to estimate experimentally state of mine workings being supported under the conditions of areas disturbed by coal mining. Methods. The studies involved field instrumental ...
    • Destruction of rocks by the non-explosive depleting compounds during mining 

      Sakhno, S; Kobylianskyi, B; Sakhno, I (National Mining University, 2016-03-30)
      Purpose. Justification of the possibility of non-explosive coherent rocks destruction while carrying out stratal underground mine workings on the basis of the set of dependencies describing changes in physical and mechanical ...
