Authors: A.S. Kuchin, Candidate of Technical Sciences, State Higher Educational Institution «National Mining University», Doctorate of the Department of Mining Surveying, Dnipropetrovsk, Ukraine


The results of the analysis of displacement and horizontal deformations above the moving coalface are presented. The size of mined-out space with compression reaching maximum is determined. Diagrams of the ratio of maximum horizontal deformation from stress-strain during the increase of the mined-out space are presented.
