Abstract

A support member (10) capable of bearing an axial com­ pressive load may be used as a support in an underground mine. The support member (10) comprises an elongate tube (12) of a flexible plastics material divided by dividing walls of the flexible plastics material into a plurality of compartments (14) running the length of the tube (12) so that the tube (12) divided into compartments (14) has a honeycomb structure. Some or all of the compartments (14) are filled with a particu­ late filler material (20) such as sand.
