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...
