Design Procedures for Coal Mine Tunnels.
NTIS: PB/83-197624 :49 pages
Although coal mine tunnels such as the main haulageways or roadways are the lifelines of coal mines, little attention has been paid to them in the United States in terms of preconstruction planning and design. This report summarizes the results of a 3-year research project aimed at improving the design procedures for coal mine tunnels. A new design approach was developed for this purpose and roof-support design charts were prepared for mine tunnels and their intersections. Analytical studies, "base friction" model experiments, and in situ rock stress measurements were performed during this research.
