Beta Release: This software has not fully completed NIOSH's rigorous testing but is considered fully functional. Because of the high level of interest from numerous stakeholders this beta version is being made available now. Send comments to mining@cdc.gov.

STOP (Support Technology Optimization Program) is software to assist in making engineering decisions regarding the selection and placement strategy of various standing roof support technologies. The software includes a complete database of the support characteristics and loading profiles obtained through safety performance testing of these supports at the NIOSH Safety Structures Testing Laboratory.

Support design criteria in the form of the required support load density at a specified convergence can be established from four options: (1) a database of measured ground reaction data from various mines or ground behavior information inputted by the user, (2) determination of loading requirements based on a detached roof block or rock failure height, or (3) criteria based on the current roof support system, and (4) arbitrary criteria set the by user. Using these design criteria, the program will determine the installation requirements for a particular support technology that will provide the necessary support load density and convergence control. Optimization routines are also available to determine the most efficient support design for a user specified support installation. Comparisons among the various support technologies are easily made including graphical analysis of relevant support parameters.

New to version 4.0:

  • Updated user interface
  • Simplified procedure to accommodate uncontrolled convergence
  • Support database updated (currently used and unused)
  • Ground reaction curve database update

Installation instructions:

  • Download and unzip the installer to a local folder.
  • Open the Installer folder and run stop_setup.msi.
    • Note: Administrative rights are not required for single user installation.

Audience: Mine operators
