In Kushiro coal mine, Taiheiyo Coal Mine Co. Ltd., hydraulic iron props have beers applied successfiy since 1959, and hobels since 1960.
A considerable increase of output per manshift has resulted from these mechanization in thin seams. Then we began to use Tandem hobels and MKSP-LIU type selfadvanced roof supports in our thin seams to get more increased productivity, and obtained some good results. The auther report in this paper, the new mechanised organization of winning, several technical and economical data.
The auther also discussed the problems of thin seam mechanization, which we must dissolve in future to get a much more high productivity in our coal mine.
