Download or read book Information Circular 9466 Geologic Hazards and Roof Stability in Coal Mines written by Gregory M. Molinda and published by CreateSpace. This book was released on 2013-11 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. underground coal miner faces a continuing hazard from the fall of roof. At the root of many injuries and fatalities are weak or defective roof strata. Throughout mining history, millions of miles of entry have provided exposure of every conceivable geologic roof hazard. This report describes the geologic origin, association, and potential danger from the most common hazards. Discussions of weak rock include drawrock, rider coals, head coal, stackrock, and stream valley effects. Discontinuities, or roof defects, are described including, clay veins, slickensides, joints, and paleochannels. A number of examples from U.S. coalfields are used to document geologic structure and associated hazards. Roof fall analysis is a methodology used by NIOSH for hazard recognition and prevention; its application and benefit to the industry are discussed.

This book was released on 1982 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 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.
