“…In cases where additional, external impacts generate dynamic loads on buildings, deformation analysis enables determination of the direction of such impacts, as well as their value and intensity. An example of this is the behavior of a headframe during the dynamic formation of a post-mining trough on the surface of a mining area [1]: the shape of the trough, as it changes over time, determines the value and direction of tilt of the headframe on the surface. These quantities define the deformation of the object and are assigned to the axis of the building in the form of a horizontal projection of the inclination vector and its azimuth.…”

Remote technologies, including laser scanning, are frequently employed to acquire data describing the geometric condition of engineering objects. The automation of point cloud processing becomes essential for promptly and reliably monitoring changes in their current shape. The article introduces a methodology for generating point clouds, focusing on detecting the shape of the object’s cross profiles and subsequently determining its inclination through simulations and real data recorded using terrestrial laser scanning technology. The simulations enabled the identification of variations in the characteristics of changes in the course of the axis of a slender structure, depending on the adopted calculation method. Point clouds derived from measurements of complex engineering objects facilitated the validation of the assumptions of the proposed methodology. The suggested solution enables the semi-automatic extraction of data from point clouds and the assessment of the geometric state of engineering object axes based on multi-temporal point clouds.

“…protecting and revitalising historic buildings, which are often sacred objects, requires a particularly great deal of effort and expertise, also related to legislation. in poland, mining extraction has been carried out under several such buildings, ensuring the conditions for their continued operation through appropriate mining prevention methods [26] as well as construction ones [13,14,18]. of particular interest is the innovative structural protection of the church building in ruda Śląska -wirek, which allowed the building to be used without danger [26].…”

Assessment of dAmAge cAuses of monumentAl objects locAted in mining AreAs -cAse studyThe paper presents an example illustrating the problems of assessing the causes of damage that occurred to building structures located in mining and post-mining area. it is frequently necessary to determine whether probable damages came from other, non-mining causes or were caused by underground mining. This issue is particularly significant when it comes to monumental, historical objects because the cost of repairs is typically very high. The purpose of this work is to demonstrate, using the magnificent church as an example, that damage to building objects situated in mining areas does not necessarily result from mining activities. As a result, every such situation should be thoroughly evaluated to determine whether such a relationship exists. For the assessment of such a conclusion, multidirectional studies in the framework of this work were carried out: hydrogeological, mining and technical factors that cause the damage to the church building in question were analysed.

“…Deflection of a building is usually considered as a process altering technical properties of buildings, including dynamic properties [8,9] and reducing the comfort of their use [10,11]. Deflection is often regarded as load while analysing serviceability limit states [7,12] and ultimate limit states [13,14,15], the additional stress-strain measure of floor [16] is also taken into account. For the latest case combinations of load, including deflection as permanent load and seismic load as variable are particularly important [17,18].…”

Mining exploitation of hard coal is conducted in the Silesian region in Poland. As a result, the post-mining void is formed which leads to non-uniform lowering of the ground level. Consequently, thousands of buildings are vertically deflected. This type of deflection causes troublesome use of buildings, underestimates their value, and in extreme situations leads to exceeded limit states. Therefore, such buildings are rectified by non-uniform elevations by means of jacks. On the basis of the analysed rectification processes, the method of determining the deflection of a building and the height of elevating its corners were presented depending on the type of building. This paper is a review of methods of determining the deflection of buildings having different sizes: single-storey buildings, single-storey buildings with a usable attic, two-storey buildings, and 11-storey buildings. Moreover, specific situations were analysed, in which the elevation height was determined by a range of additional works performed during rectification. This review was used to develop guidelines for determining deflection values and specifying the height of non-uniform elevation of corners.
