Abstract

The article presents subject matter related to the assessment of the suitability of the built-up area, including the occurrence of sinkholes on the surface. The investment plot, which is the subject of the analysis, is located in the central part of the Upper Silesian Coal Basin, where shallow exploitation of coal seams was conducted in the past. At present it is a post-mining area, located at a large distance from active mines. It has an attractive administrative location and good transport connection with the main road connecting the cities of the Silesian agglomeration. These advantages make it particularly attractive in terms of use for various types of investments. The geological and mining factors are not favorable in the area in question, mainly due to the shallow mining exploitation conducted in the past and the access excavations on small depth and an unknown method of liquidation. These reasons are the cause of some restrictions in the use of construction, for which taking the appropriate solutions is recommended. According to the study of (Rules... 2009), the category of mining land should be defined for the areas of liquidated mining plants due to the limitation in construction use. The authors of the article made an attempt to determine it, and they analyzed the geological and mining conditions for this purpose, mainly including mining exploitation conducted in the past. On the basis of the obtained results and own experience, the type of expected hazards and its assessment were determined The probability of the occurrence of the inclusions according to the Chudek-Olaszowski method (Chudek et al. 1988) was assumed as a measure of the hazard.

Abstract

The post-mining areas due to the difficulties of those, often associated with expensive activities, usually take the form of wasteland. In contrast, unavailable, unused and alien areas the mentality of residents, are identified with empty space. The purpose of the authors was to answer the question: Are post-mining areas becoming empty spaces? Her research basis was changes in the functioning of post-mining areas and empty spaces in Katowice – a city with a long-standing mining tradition. Using GIS tools, a spatial analysis was carried out to determine the empty spaces functions and the perceiving of the post-mining areas by residents or users of a given district nearby.

Abstract

Post-industrial areas are an area of concentration, penetration and shaping the economic, social and environmental zone. The strategic goal of transforming post-industrial areas should be to obtain a new, dynamic and favorable state of equilibrium for a given area, as well as its surroundings after cessation of operations. The purpose of the article is to indicate the possibility of adaptation of post-industrial areas, especially after exploitation of the mineral, to perform new functions. The direction and the purpose of the recultivation and planning actions to a large extent may be influenced by specific social and economic conditions affecting the competitiveness of each and individually treated fragment of space.

Abstract

The rim of a post-exploitation basin is a particularly dangerous zone for buildings. This is due to the impact of mining on the nearby buildings, which persists even after exploitation activities are finished. The rim of the basin remains constantly deformed. This paper presents numerical analyses of buildings located in Marklowice (Silesian Voivodeship, Poland). They are located in an area that was exploited for mining, above the initial exploitation edge on the rim of the basin. The area of the analysed buildings was geodetically monitored during mining works. The results of the measurements allowed the observation of changes in terrain deformation indicators, together with the determination of the settlement’s final values after the operation was completed. Knowledge of the results enabled the preparation of numerical analyses of buildings with the use of the finite element method (FEM), the purpose of which was to determine the residual stresses in the structures after the end of the exploitation. The results are presented in the form of stress maps, which show changes in the internal forces in buildings left by mining operations. Specific examples are used. Two residential two-storey buildings were analysed; they were built using traditional brick methods, with a single-storey outbuilding. All of the analysed buildings are located in the mining commencement zone, in which the deformation of the surface has not faded away.
