Abstract

The aim of the doctoral dissertation is an analysis of application of building site categories for engineering-geological purposes and undermined areas. The motivation behind the work lies in insufficient utilisation and application of building site categories for the purposes of better development management and planning in areas affected by underground coal mining. Building site categories represent the categories of mining hazard taking into consideration the vertical deformations via declination, horizontal deformations via horizontal unit deformation, and tensile and pressure deformations of the ground expressed by means of ground curvature. A partial objective of the work is to apply the building site categories as point information (data expresses as points). An evaluation of nine churches, i.e. structures that have survived longer time periods, in a subsidence trough has been included in the work. Another objective of the dissertation is to evaluate the building site categories as linear information (data expressed as lines). For this reason, regular monitoring of roads that is used only for road repair purposes has been selected as in this dissertation thesis it is used to rectify prognostic maps of subsidence influence. The third objective of the work is spatial evaluation of the building site categories. This has resulted in an evaluation of the prognosis, and a new map with three zones of hazard (suitable, conditionally suitable and unsuitable). All the findings have been related to the existing and planned built-up areas according to the land use plan. Another objective is to evaluate the building site categories on slope deformations. This concerns twenty slope deformations, where changes in the subsidence-induced slope angle have been identified. The last objective of the work is to evaluate the building site categories as one of the multi-factors in overall assessment of land use plans in mining areas. Apart from building site categories, various information, such as engineering-geological zones, rock workability, flood plains, radon hazard and slope deformations, have been used to produce a new map of hazard, namely a geo-multi-factorial map for land use planning purposes in mining areas. The dissertation has shown that the utilisation of building site categories, evaluating ground deformation, is vital for possible complex assessment of the area in the undermined landscape. All the findings are based on practical case studies of partial objectives, and their application appears as optimal and crucial for such anthropogenically influenced areas.
