Abstract
As deeper seams are continually mined, methane liberation will continue to increase and must be monitored effectively. To effectively monitor and develop appropriate control technology, methane liberation patterns must be known. The Bureau of Mines recently completed a study to identify specific face methane liberation patterns during longwall mining. Two longwall faces were surveyed. Both had high methane liberation rates. At one longwall face, most of the methane was liberated during cutting of coal by the shearer mining machine. At the second face, a significant portion of methane was from total face and floor liberation. An effective methane monitoring system would be different for each longwall panel because of the differences in liberation.
