ResumoEffective control of land subsidence requires reliable predictions of ground deformation caused by mining. Apparently the extent of mining impacts are affected by the scale of disturbances of the rock strata. Intensive mining operations in the vicinity of the town Ruda Śląska in the Upper Silesia Coalfield began in the 19th century, so the rock strata in this area is now strongly disturbed. Vital information about the behaviour of the disturbed rock strata, required for the purpose of predictions, is obtained from geodetic measurements and surveying of subsidence troughs in the area. The surveying data enables us to find the relevant parameters in the Budryk-Knothe’s theory for the given area. This study briefly summarises the processes occurring within the rock strata during the mining operations, in the context of the mining history, geological structure and rock properties in the neighbourhood of Ruda Śląska. Of particular interest are the results of geodetic measurements of subsidence due to mining operations continued underneath the town district of Wirek, in the period from 2005 to 2008.
