Movements of rock mass and soils, resulting from underground mining extraction are likely to cause mining damage to building structures, which is a serious issue in urbanised Europe. 1, 2 The better knowledge of mining-induced surface and rock mass deformation could provide to more accurate prognosis, but the estimation of the values and distribution of horizontal movement are still unclear. 3, 4, 5, 6 Describing the horizontal movements caused by mining operations, the dependency provided in 7 is used. It asserts that there is a linear relationship between the vertical movement vector u and the tilt vector T. The relationship can be described with the following formula:(1) u=− B∙ T where B is the horizontal movement or horizontal strain factor with the value depending on the local mining and geological conditions. 8
