Abstract
Abstract
Paper describes an example of underground mining exploitation which in a thick seam divided into a few layers has been conducted. It took place in the years 2013 – 2018 in the southern part of Poland, in the Upper Silesian Coal Basin and was carried out by the use of four, high longwalls with a roof rocks cave-in. In article a reprognosis of the mining exploitation impacts on a terrain surface has been done. For this purpose the EDN – OPN computer program was used. Extraction influences by the use of the Bialek’s formula for subsidence have been predicted. There the subsidence, inclinations and horizontal strains after the end of every exploitation stage have been calculated. Thanks to that it is possible to determine the expected range and size of exploitation impacts on a terrain surface and the objects located on it.
