To provide longwall operators with a method to predict methane emissions from panels with increased face width. To predict the methane emission consequences of mining longwall panels of greater face width, it was first necessary to measure current emission rates to determine if a general increase in methane emission levels occurs progressively during the mining of longwall pass. A production time study was conducted to correlate methane emission data to mining activity and shearer location on the face.
