Formation of the horizontal displacement during the lava withdrawal from floating furnace
Authors: A.S. Kuchin, Candidate of Technical Sciences, State Higher Educational Institution «National Mining University», Doctorate of the Department of Mining Surveying, Dnipropetrovsk, Ukraine
Annotation:
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.
