Numerical modelling of subsidence induced by underground coal mining
Abstract
The subsidence induced by single panel coal extractions has been calculated with continuum and distinct element stress analysis. Nonlinear material models in programs FLAC and UDEC, which allow a more realistic representation of the behaviour of the roof strata, reproduce the observed qualitative change in subsidence profiles that occurs in the transition from sub-critical to super-critical panel widths. The programs therefore have the potential to provide reliable subsidence prediction in new geological and mining environments.
