It has been found that a major problem in longwall mining is contamination of the face intake air. Using typical mining cycles and respirable dust data to analyze the potential impact of respirable dust exposures, homotropal ventilation as a possible cost- effective technique for reducing intake respirable dust contamination was investigated. The analyses showed respirable dust exposures on any cutting cycle could be reduced using homotropal ventilation. During a tailgate-to-headgate cutting cycle, e.g., homotropal ventilation was predicted to reduce the shearer operator's exposure by 40 pct. After theoretically establishing the potential benefits of homotropal ventilation, researchers expanded the effort to (1) quantify the benefits and potential problems of homotropal ventilation with underground evaluations, (2) document the ventilation systems and mining techniques utilized by homotropal mines, and (3) provide technical information to the mining industry on the use of homotropal ventilation.
