Summary of results of investigation made at six coal mines where representative methods of working Arley seam under typical natural conditions are practiced; at partially stowed machine faces, roof was more broken than at completely stowed hand faces; determining factors appeared to be higher speed of advance and less, effective stowing associated with machine mining. Before Manchester Geol and Min Soc.
