Abstract

The equ ipment is for the introduction of pillars into backfill material, particularly as used to reinforce mine gallery junctions. It comprises a vessel of flexible material whose dimensions and shape are those of the pillars to be placed in position, and with a filler pipe. The vessel (1) is of porous cloth (11) retaining the backfill material. The cloth can be cotton, jute linen or mixed, also incorporating synthetic fibres if necessary. It can be fireproof, and roughened on one face at least.
