Download Case Study

Murray Engineering was engaged to install a second vertical cable from the surface of a working mine, with zero interruptions to daily mining operations or ore haulage. The Murray Engineering team designed and installed concrete footings, a winch assembly, sheave assembly and final support structure. Murray also developed the installation methodology, and commissioned the project on site, including civil works.

The mine site is the deepest operating mechanised mine in Australia. The client recognised that this would result in a huge cost to install electrical cable via traditional methods (i.e. decline and service hole).

The depth of the mine required specialised engineering in order to safely complete the cable lowering operation. This also incorporated an engineered and certified cable clamp design developed by Murray Engineering. These clamps are smaller in dimension than traditional clamps used for vertical cable installations, and resulted in a 30% reduction in borehole size. Critical infrastructure components were manufactured in our facilities ahead of time, to minimise installation time on-site.

The ability to install the cable vertically without shutting down areas of the mine, combined with a reduced bore-hole size that minimized drilling time, resulted in significant cost savings for the client.
