Abstract
Primary and supplementary support of coal mine gate roads has become an area of great interest as coal production from advanced longwall technology has increased in the United States. Variations in geology, stress conditions, and mining geometries all affect support selection decisions. With the goal of improving mining safety, the U.S. Bureau of Mines (USBM) is investigating the use of cables as a support option for longwall gate roads.
