The subject of this article is a two-storey, detached residential building. The building's structure is characterized by concrete sealing?s, load bearing walls made of brick and basements. The building has been deflected from the vertical as a result of a multiple underground exploitation which in the hard coal beds has been conducted. It is planned a continuation of mining exploitation in the area of the building. Use of a deflected object is connected with many inconveniences. Moreover, its market value falls do...

In the article an example of underground mining exploitation of hard coal deposits has been presented which by some mining plant in Poland has been conducted. Hard coal extraction took place in three seams numbered 338/2, 341, 358/1 which at the medium and great depths have been located. Exploitation was conducted by use of the longwall system with roof rocks cave-in. This exploitation caused an occurrence of curvatures on a mining terrain surface. The curvatures values on base of the surveys results have been cal...

In this article was shown a methodology of obtaining the average graphs of mining terrain curvatures caused by multideposit exploitation of hard coal which was conducted at the great depth. An instance of exploitation comes from the mining plant which was established in the borders of The Upper Silesian Coal Basin in Poland. Hard coal exploitation was conducted in the years 2001 ? 2011, in three coal beds 338/2, 341 and 358/1, at the depth of 600 m, 635 m and 1000 m. Influences of mining exploitation were observed...

In this paper were presented the results of geodesic measurements which took place in the years 2001 ? 2011 and were carried out by some hard coal mine, which is located at the Upper Silesian Coal Basin in Poland. This mining plant was conducted an exploitation of hard coal in three coal beds named 338/2, 341 and 358/1 which were respectively located at the average depth amounts 600 m, 635 m and 1000 m. In order to observation of the impacts of multi-deposit exploitation conducted at the large depth, the measuring...

The article presents the way of conducting a forecast of leverages of underground mining run by longwall fronts in three deposits of hard coal on the area. The forecasted values of subsidences, inclinations and curvatures of mining area were calculated by the Budryk- Knothe theory with the use of typical values of its parameters, namely, a coefficient of subsidence of floor rocks equal to 0.8 and tangent of scope angle of main leverages amounting to 2.0. The forecasts of indicatorsпїЅ values of area deformation we...

Nowadays surveying пїЅ geological departments of Polish coal mines conduct forecasts of leverages of underground mining on area and construction works based on J. BialekпїЅs formulas including, among others, distant leverages, reactivation of old workings and mining margin. The objective of this article is the adequacy study of the conducted forecasts of area deformation in this way with relation to real values of deformation indicators confirmed by surveys. For this purpose, an example of a really terminated expl...
