Problem of failure of hardened and tempered sections for roadway supports
Properties of hardened and tempered steel sections installed on each side of roadway line of strutting inclined to roadway floor; utilization of load bearing capacity of roadway support sections from viewpoint of stability is likely to be provided by smooth concrete covering or by binding with mortar dirt.
