The theory of professor Stanisław Knothe has become a basis for practical prognostic calculations of mining impacts and, by the same token, it has allowed initiation of large scale exploitation of major coal, salt and metal ore deposits located in the protective pillars of towns and important surface constructions/facilities. The theory of professor Knothe is being successfully applied by the Polish and international mining industries for over sixty years. One can certainly say that it is one of the best known and internationally recognized achievements of the Polish mining science. The article presents a brief summary of contemporary applications of the Knothe theory in calculation of rock mass and surface subsidence not only in their classic form relevant to calculations for mining coal deposits. The solution presented here is based on a mathematical model of deposit impacts and it includes, among other things, subsidence caused by fl uid deposit exploitation, heat extraction in deep geothermal applications and the uplifting of land surface caused by changes in mining water levels in closed hard coal mines.
