DOWNLOAD EBOOKThe purpose of this study is to identify and assess those geological factors that are associated with and promote roof problems in undersround coal mines in the Crowsnest Pass area of the southern Canadian Cordillera. Another objective is to relate the observed roof conditions to the sedimentology and the kinematics and dynamics of deformation of the coal measures in order to develop geological criteria for predicting roof conditions.
