The low capital cost, rapid deployment and simple operation of the BHH system can minimise the requirement for underground haulage capacity in situations where existing infrastructure is distant to mining areas. For long strike ore bodies, the BHH system can be installed at predetermined locations along strike, providing hoisting capacity and services access to underground.
Capacities
The BHH system has been used at the Glennies Creek Colliery in NSW to hoist shaft construction waste rock from 330m depth at a rate of 450 tonnes/day (160k tpa).
The scalability and flexibility of the system allow cost effective haulage capacities to 350k tpa using a 6 tonne capacity conveyance, 2.44m diameter raise bore hole and to depths of 650m.
