TRčKOVA, J.. Experimental 3-D modelling of surface subsidence affected by underground mining activities. J. S. Afr. Inst. Min. Metall. [online]. 2009, vol.109, n.12, pp. 739-744. ISSN 2411-9717.
This paper describes the method of modelling rock mechanical problems on experimental models. Based on an actual experiment used as an example, assessment of the surface deformation due to undermining, the extensive possibilities of using a 3-D physical model and application results in practice are demonstrated. A special method of modelling the underground mine progress by using paraffin melting is presented.
Keywords : undermining; subsidence of surface; 3-D experimental model.
