• Description:
  Unplanned tailgate collapses and difficult mining conditions in U.S. longwalls have necessitated the use of innovative tailgate support systems. Severe ground movement induced by longwall loading has caused operators to utilize secondary support systems that can match yield and strength requirements with expected ground reactions. In 2020, the National Institute for Occupational Safety and Health (NIOSH) updated the Support Technology Optimization Program (STOP) in order to better evaluate these secondary support systems by providing mine operators with a simple and practical tool to make engineering decisions about the selection and placement of various secondary support systems. This update implements important changes to STOP's user interface and functionality and significantly enhances the use of ground reaction curve design criteria. The paper provides examples of using the 2020 version of STOP to evaluate a current standing support system followed by using the ground reaction curve design criteria at this case study mine.
