Multiplication Analysis of the Cause, Form and Extent of Damage to Buildings in Areas with Mining Impact

Abstract

Abstract This publication is a summary of all tasks carried out in recent years of research, calculations, simulations and analyse related to the performed research on parameter analysis that affect the form, scope and cost of removing damage in buildings and structures in areas with mining impact. The analysed problem is interdisciplinary and contains legal, geotechnical, engineering - mining, construction, material and economic analysis. The ground reaction forces were analysed for buildings and structures in the mining area. Coordinating activities of the land model, foundations and construction of buildings and structures in the mining area were adopted and the distribution rights and changes in additional reaction forces of the structure in the mining area were analysed and various factors which affect the construction damage were indicated. Problems were also identified in the mining impact forecasts that affect the design scope of new engineering structures and the impact of existing buildings and structures. The influence of various factors was analysed and additional dependency formulas were proposed, which are needed for current calculations and analyses of the scope and costs of strengthening the structure or its modernization. Based on the output data and the analysis of the results of the empirical examination of selected buildings, the determination of all factors affecting the technical condition of the building erected in the areas with the impact of mining operations. Classification according to currently used guidelines and clarification of new attributes affecting the technical condition of buildings and structures (typical and modern geometry of the building’s structure, type of foundation, type of construction protection, type and stiffness of the structure). Backward analysis of damages (their temporary changes) identified as factor affecting the current state of engineering objects.
