Introduction Where do we find the most exclusive air in the world? Page 2
Mine Ventilation / 1 The most exclusive air in the world is actually found in deep underground mines Fresh air is being pumped down through ventilation shafts to generate a constant flow of air stream to the underground workings to dilute and remove dust and noxious gases to regulate temperature Underground Mine EXAMPLE Page 3
Mine Ventilation / 2 Cost-intensive necessity for underground operation Mine Ventilation Systems Ventilation systems normally operate 24 hours a day, 365 days per year They account for 25% to 40% of the total energy costs of a mine operation US$ 20 to 30 million per year running costs for mine ventilation Underground Mine EXAMPLE Significant capital expenditures to build ventilation shafts and to install ventilation equipment Page 4
Challenges Mining operations take place at ever greater depths Lower mineral grades and minable ore bodies which can be found only in greater depths of the earth crust Much more bulk material has to be blasted, dug and hauled to the surface Mining companies have to consider tighter environmental, work safety and health legislations Limits regarding exhaust emissions of diesel engines Maximum values for noise and vibration loads for mining equipment operators Page 5 To increase the number of diesel trucks can t be the answer
A new approach is needed Implementation of electrical drive systems for underground vehicles Based on our proven drive systems for electrical vehicles, we have adopted standard components and use them as a new drive system in existing underground mining trucks This is part of our business strategy to improve the working conditions in deep mines to increase production and productivity to enable mining in ever greater depths Page 6
ical drive system for underground mining truck Architecture Four-wheel driven, based on proven systems and adopted for mining 4 electrical wheel motors Double-alternator Precise speed and torque control for each wheel Advanced slip/slide control ically supported steering Reduced tire wear by exact turn control Optional: energy storage modules foreseen Page 7
Prototype development for underground mining truck Time Line We are currently well on schedule 2016 2017 March 2016 May 2017 Mid 2017 Wheel Motor Alternator Kick off Converter SysTest Shipmt Implement Field Test Software Page 8
-electric vs. pure diesel trucks Benefits - The use of diesel-electric trucks requires less mine ventilation E-Trucks are faster because of higher efficiency More diesel power can be used for propelling Shorter cycle time leads to higher productivity Less maintenance saves costs and enhances operating hours à higher availability Reduction of maintenance expenditures by around 15 percent is expected Less heat and exhausts leads to more favorable environmental conditions Page 9
