Abstract: Described herein are methods and apparatuses for traceable electrical conductors, and, in particular, to electrical conductors that include a strength member, including: a core formed of a composite material, an encapsulation layer disposed around the core. A traceability feature is incorporated in at least one of the core or the encapsulation layer. A conductor layer is disposed around the strength member such that the traceability feature is disposed beneath the conductor layer.

Abstract: A method for lining mining and tunnel constructions with a support material (20) comprises the steps of: •a. providing a plurality of lay wires (24) in the long direction; •b. providing a plurality of stay wires (22) in the cross direction, the stay wires making intersections with said lay wires (24); •c. providing knot wires (28) to attach the lay wires (24) to the stay wires (22) in at least some of the intersections so as to form the support material; •d. installing the support material (20) against a ceiling or a wall of a mining or tunnel construction by means of bolts.
