Influence of Discontinuous Linear Deformation on the Values of Continuous Deformations of a Mining Area and a Building Induced by an Exploitation of Hard Coal Seam

In this article, the impact of a ground step on residential building and mining terrain has been presented. Influence discontinuous linear deformation by changes inclination curvatures’ values (continuous deformations) observed. Discontinuous continuous deformations have caused an exploitation 405/1 hard coal seam, located at depth 550 m. Extraction was carried out with use longwall system to south building. A occurred parallel north wall had height 0.2 The calculated basis results geodesic surveys. Vertical displacements horizontal distances between measuring points in building’s walls measured. Points two perpendicular directions (parallel step) stabilized. observational network consisted 12 (3 each direction, walls). Research shown that inclinations curvatures different terrain’s surface buildings, which means process takes place way obtained indicate occurrence near reduces direction its longitudinal axis, it increases it.
