This book was released on 1954 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation of the mine accidents in the State of Illinois from 1882 to 1953 reveals the fact that there have been 8,410 men killed in mining accidents ... Further inspection shows that 4,019 deaths or 47.79% of the total number killed, have resulted from falls of roof or rib ... Much research concerning the problems of roof control in coal mining has been undertaken ... Very little work has been done to evaluate the fundamental constituents of the roof strata. In an occupation where the greatest danger comes from materials liable to fall, an understanding of the physical, chemical and geological make-up of such materials is of prime importance. This report was undertaken in order to investigate some properties of shales forming mine roof by simple laboratory and field tests, in order to contribute to the knowledge of certain basic characteristics of roof shales and to develop methods for evaluating samples obtained in exploratory drilling.

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.
