  • Description:
    The Bureau of Mines constructed a mine roof simulator in 1980 to conduct research on full-scale roof support structures under precisely controlled load conditions. The simulator is a bidirectional active load frame that can uniquely apply controlled forces or displacements in both the vertical and horizontal directions. Using this simulator, the Bureau of Mines has been conducting research on various types of underground roof support structures. The objective of these research efforts is to evaluate load transfer mechanics in order to develop methods to improve the selection and design of these support systems. This article presents a synopsis of the parameters investigated and research results for longwall shield supports. It is concluded that through these research efforts, the Bureau of Mines has advanced the understanding of shield mechanics and developed improved methods for performance testing of longwall supports.
