• Media Type: D

• This report is prepared in five sections. After this introduction, conclusions and
recommendations from the study are presented in section 2.0, followed by a discussion of
subsidence mechanisms in section 3.0. Geologic conditions and subsidence
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 over the Dove Gulch study area.
