Abstract

A numerical procedure was developed, based on the well-known finite element method. This model incorporated concepts related to the mechanics of strata deformation and empirical indices associated with subsidence engineering. Different material behavior models and failure criteria were employed in an attempt to determine the surface areas most affected by underground mining. Deformation zones based on empirical parameters were defined in the overburden in an attempt to simulate theoretical and observed strata deformation characteristics. Accurate subsidence and horizontal strain calculations verified the modeling procedure with respect to the strata deformation zones. Finally, the model was used to predict vertical and horizontal movements, based on empirical parameters available for the Appalachian region.
