Mining Project: Calibration and Verification of Longwall Stress Models

Project DetailValue
Principal Investigators
  • Jeffrey K. Whyatt, NIOSH, 509-354-8068
Start Date10/1/2010

This project will provide a case study and exploration of options in assessing ground safety with analytical stress analysis tools in design of longwall coal panels consistent with MSHA guidance. This work will promote development of standards and conventions for appropriately conducting such analyses, providing much-needed context for analysts working within the framework of MSHA guidance.

Program Area
Keywordsground control, mining

Research Summary

The project is executed as part of the NIOSH Office of Mine Safety and Health effort to reduce ground failure fatalities and injuries in the mining industry. This project will contribute to the NIOSH Office of Mine Safety and Health Research Program. The major outputs will be peer-reviewed and publically available publications demonstrating and developing proper practice in assessing ground failure hazards consistent with MSHA guidance. These developments should also have application to other types of underground coal mining, and provide some insight into similar mining methods applied to other commodities. The intermediate outcomes will be to facilitate development of sound engineering practice within the framework provided by MSHA guidance and, possibly, extension and/or refinement of that guidance. Ultimately, the project will support assurance of ground safety by design in the nation's coal mines.
