This Bureau of Mines report presents a finite element analysis of roof stresses associated with a 4-foot-high by 18-foot-wide underground coal mine entry. This analysis starts with known loading conditions determined in an underground coal mine in West Virginia and is extended to other possible underground loading conditions. The roof failures predicted by the finite element analysis under known loading conditions correlate well with the roof failures observed underground. The most probable failure modes are identified for the various loading conditions considered. Various failure preventive measures are discussed.
