Abstract
The face ventilation plans for extended cut must be submit by the Coal Mining Company to the Mine Safety and Health Administration (MSHA) for evaluation and approval. This evaluation process could be enhanced by having the opportunity to perform an experimental and a numerical study of the proposed ventilation arrangements. These studies could provide a clear determination and adequateness of the ventilation in the face area. In this paper, the authors will present and discuss the data collected during the experimental study of face ventilation scenarios using a scaled physical model (1: 15), equipped with in-house designed and developed Particle Image Velocimetry (PIV) 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.
