• Description:
  The face ventilation plans for extended-cut operations must be submitted by the coal mining company to the U.S. Mine Safety and Health Administration (MSHA) for evaluation and approval. The ability to perform an experimental and/or numerical study of the proposed ventilation arrangements could greatly enhance this evaluation process. These studies could provide a clear determination of the adequacy of the ventilation scheme in the face area and flag any possible problems. In this article, the authors present and discuss the data collected during an experimental study of face ventilation scenarios using a scaled physical model (1:15) and using an in-house designed and developed particle image velocimetry system. The face ventilation arrangements evaluated in this paper are typical of the plans submitted to MSHA for approval by Eastern Kentucky coal companies that utilize continuous mining machines not equipped with scrubbers or mechanical face ventilation enhancing devices.
