This study will present the experiences of the first battery-powered scaling machine, that has been in production operation for a year in one of Boliden´s mines. The scaling process in a mine environment involves the use of a dedicated scaling machine to remove loose falling rock after blasting. When the machine enters the tunnel where the blast took place, is not secured. This means that the safety requirements are very high on the machine. The scaling machine has been developed by Jama since the mid-1990´s and has now been developed with battery-power in collaboration with Epiroc. The study will review Boliden´s lessons learned about this significant paradigm shift and the various aspects of the transition to battery-power from operators and maintenance managers. It is of interest to understand how Boliden has redrawn the map to implement new technology, challenges and how the operator experienced differences from diesel scalers to battery scalers and if there have been any special training needs or adaptions. By highlighting these various aspects of the first batter-powered scaling machine implementation in a mining environment, the study will provide insight into the potential and challenges of introducing new technologies and promoting sustainable and environmentally friendly scaling methos in the mining industry.
