Abstract
A comprehensive investigation was conducted into geologic features affecting coal mine ground control in western underground coal mines. This study involved a literature search for data on geologic features affecting coal mine ground control, western coal geology associated with specific geologic features, and MSHA roof fall information. Data on mining operations were collected through interviews with mining and research personnel. Selected mines were toured within 10 coalfields in Utah and Colorado. This final report summarizes western coal depositional environments and geological structures and describes mining and geology for the coalfields studied. All observed geologic features and conditions related to coal mine ground control are described in terms of their depositional or structural origin, morphology, diagnostic characteristics, associated adverse mining conditions, and roof control methods. Photographic documentation of these geologic features is included. Adverse geologic features and their locations are correlated with geological environments by coalfield to define their relative impact on mining operations. Comprehensive bibliographical data and selected MSHA roof fall data are also included.
