Abstract
An innovative concept in longwall tailgate support is discussed. This new concept utilizes a high-capacity roof-truss system to replace conventional wooden cribs. The first field test was conducted at the Bailey Mine and was very successful. Similar tests were installed in other mines and seams. An extensive instrumentation plan was designed and implemented in the truss test area. The test data demonstrated that the dynamic roof-truss system effectively controls the various abutment pressures caused by longwall mining. Thus, a stable tailgate entry is maintained
