SUMMARY
It is well known that the energy cost for ventilation in mines is a big part of the total energy cost there and in the construction industry the situation is similar. That is the reason for the concept Ventilation on Demand (VoD) has been developed. In this particular case the product Serpent Automatic intends to be a customized option for the single fan, single heading, with focus on energy saving and environmental control. In the market we have several options of VoD controlling the complete mine, however there are few products available for controlling the ventilation at the single face scale. Epiroc is the first company in AngloGold Ashanti– Serra Grande in Brazil to perform a trial and to do so in one single fan/single heading. By using gas sensors to detect CO and NO2, we are able to measure the concentration of blasting gases mainly, but also to have a better control of the environment during, for example, critical activities as mucking. This paper describes the system, the impact on energy consumption and experiences learned during the implementation in AngloGold Ashanti– Serra Grande in Brazil.
