Design Optimization in Underground Coal Systems: Section 1. Structural Parameters of Coal Measure Rocks. Section 2. Longwall Mining System Strata Simulator. Section 3. Design Criteria for Underground Roof-Truss Support Systems. Interim Report, April--June 1977
Research in areas related to coal mining was continued. Computer programs related to longwall mining were developed and tested. The work of sampling and testing of coal specimens continued, especially with respect to the effects of size and shape (cylinder vs cube) of the specimens on the measured properties. In addition, loading rate appears to be of some significance. The literature of supports in underground mining has been reviewed, especially with respect to roof bolts and roof trusses. The testing of functional plastic models of roof trusses by photoelastic methods has been continued. Monitoring of instrumented roof trusses in Alabama has been continued. (ERA citation 03:020916)
