Pillar cable truss system

摘要

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.
