~' characteristics are presented in section 4.0, including rock mechanics data, subsidence
parameters, and a discussion of the influence of other factors such as gate pillar designs
and surface topography on surface deformation. Predicted deformation patterns are
presented in section 5 using three-dimensional subsidence models that account for
variations in overburden thickness and subsidence parameters over the Dove Gulch study
area.
