Armouring for underground props has 3-part construction assembled from side armouring mats and central armouring mat

摘要

The armouring uses coupled armouring mats (5) for providing a framework enclosing each Bullflex prop (1,3,4), each armouring mat having longitudinal wires and transverse wires. A 3-part construction is assembled from 2 side mats (7,8) and a central mat (6), coupled together along their abutting edges, each mat having hooks for securing to a Bullflex prop, with further Bullflex props attached by hooking further armouring mats to the first Bullflex prop.
