The operating results of the collieries comprising the U.K. coal industry are analyzed for the year after the 1984-85 miners' strike. Productivity increased rapidly, mainly due to higher productivity in the continuing coal mines. Closures played a relatively small role, and were only partially concentrated on the highest cost pits. This high cost tail did not emerge immediately before the strike, but rather became much more visible due to deteriorating operating results for the industry as a whole. Productivity increases since the strike have reflected cuts in manpower, as well as increased output and have varied widely by geographical area. Copyright 1988 by Blackwell Publishing Ltd
