Practical considerations in longwall face and gate road support selection and utilization. Information Circular/1989
The U.S. Bureau of Mines has been conducting research to optimize the design and utilization of mine-roof-support systems. An objective of these efforts is to evaluate the mechanical and structural responses of various mine-roof-support systems under simulated load conditions in the Bureau's mine-roof-simulator. Underground studies are also made to evaluate the in-situ behavior of support structures. This report documents practical applications for longwall face and gate road supports that have resulted from these studies. Forty-six recommendations are made to provide assistance to mine operators in the testing, selection, and utilization of longwall face and gate road supports. Many of these recommendations offer innovative solutions to everyday problems faced by mining personnel in the control of ground in longwall mining.
