Support capacity and roof behaviour at longwall faces with shield supports
Summary Field investigations on seven U.S. longwall coal faces were carried out to examine the behaviour and interaction of roof, floor and support on longwall faces equipped with hydraulic powered supports. The most important factor in determining face stability was found to be periodic weighting and an empirical design equation was developed for support capacity. The interaction of various elements in the face system is examined and discussed.
