Abstract
A pillar cable truss system including a support cable extending between a pair of splice tubes mounted onto a geological formation such as a pillar in a coal mine with a pair of rock anchors. The splice tubes may be attached to two support cables such that sets of the support cables with splice tubes and rock anchors may be connected together to encircle a pillar. A vertically arranged elongated cable spacer tube is mounted onto the pillar with a rock anchor and includes openings through which the support cables extend. The spacer tube retains sets of the support cables apart from each other and/or allows the support cables to be installed in a crisscross pattern.
Claims21
A support structure for a geological formation comprising:
- a pair of connectors, each said connector adapted to receive a rock anchor therethrough and comprising a conduit, said conduit adapted to receive two support cables therethrough;
- a pair of rock anchors, each said rock anchor extending through one of said connectors and adapted to be inserted into the geological formation;
- and
- a support cable, each end of said support cable being coupled to one of said connectors such that said support cable extends through each said connector and each end of said support cable is configured to be coupled to another of said connectors.
A support structure for a geological formation comprising:
- a plurality of support cables;
- a plurality of pair of connectors, each said connector coupled to an end of one of said support cables such that each said support cable extends through at least a pair of said connectors, each end of said support cable being configured to be coupled to another of said connectors, said connectors each adapted to receive a rock anchor therethrough and comprising a conduit, said conduit adapted to receive two of said support cables therethrough;
- and
- a plurality of rock anchors, each said rock anchor extending through one of said connectors and adapted to be inserted into the geological formation.
