Tembo e-LV
Case Studies
Information
Low maintenance cost
Because of the regenerative braking using the e-motor, the brakes can be
used for a much longer time. No servicing on air-, oil- or fuel filters and
gearboxes or oil changes. By replacing the clutch and engine the
maintenance is minimized.
Less downtime
The higher reliability of the electrical components and the reduced number of
components guarantee that less maintenance is required and therefore less
downtime will occur.
Low operational cost
The biggest cost savings can be made on energy, while the energy needed
to provide clean and fresh air into the mine and to ventilate the exhaust
gasses and heat out of the mine will be considerably lower when only
electrical powered equipment is used. On average the cost of ventilation of
an underground mine is 20-40% of all overhead cost.
For calculating the ventilation requirements of an underground mine usually
the amount of BHP/kW of diesel-powered equipment is used, so less diesel
vehicles means less ventilation needed.
An additional advantage is that because electricity is a lot cheaper than
diesel this results in an immediate decrease of fuel cost.
No need of expensive and hazardous fuel infrastructure
The transport and infrastructure for fossil fuels to and in a mine is very costly
and potentially dangerous. With electric vehicles you can use the electric
infrastructure which is already in place for light and ventilation and the risk is
very low.
The deeper the mine, the more savings can be made.
