Tytuł: Conditions of deformation prediction in the shaft

Autorzy: Andrzej Kwinta - Faculty of Environmental Engineering and Land Surveying University of Agriculture in Krakow

Streszczenie:

Mine shafts shall function safely according to their destined use over the entire time of a exploitation. In order to secure the shaft function protection pillars are established around it within which pillars mining is not allowed or only on special conditions. Forecasting a continuous shaft deformation due to mining under Polish conditions is carried out by means of the modified Knothe theory. Due to various modifications of theory and its parameters are changes the quality of the prediction. In the paper was presented different functions of influence radius in rock mass.
