On bord or slightly off bord faces Dranyam machine achieves considerable improvement in coal-sizing over Anderton Shearer-Loader, while possessing almost equal simplicity of operation and giving comparable productivity; where coal cleavage is not well defined, limited operational experience to date indicates that only marginal improvement in coal-sizing is possible; limitations of machine and lines of development which would widen field of application.
