ABSTRACTThe modelling of subsidence development is presented as a convenient subsidence prediction technique. The proposed prediction method of mining-induced subsidence development applied at the Slovak Handlova Coalfield to mining longwall operations is based on a prediction method by Knothe. Theoretical calculations in modelling were proofed using data collected from surface monitoring, from which the appropriate site-specific parameters were obtained. The results, with accuracy analysis in subsidence development modelling, have confirmed the applicability of this method in deformation surveying practice.
