Strategic mine planning optimization for the potential transition from open-pit to underground mining at Akyem Gold Mine, Ghana

The transition from open-pit to underground mining operations is a frequently occurring procedure for mines around the world. The Akyem Gold Mine in Ghana is an example, where the transition is to be optimized with regard to the significant reduction in yearly throughput. The current processing plant is commissioned to efficiently process up to...

Study on the Impact of Trolley Assisted Haul Trucks on Strategic Mine Planning in Open Pit Mines

Trolley assist is a system in which haul trucks in open pit mines are propelled by electric energy along a designated haul road segment. This can lead to high savings on fuel costs, productivity, CO2 emission and engine life, but is associated with limitations on mine planning. The purpose of this thesis is to determine how trolley assist can be...
