R&D work regarding the innovative mine transportation system, planned to be powered by the three-phase busbar, developed within theRFCS project "Increase of mines efficiency and health protection through the innovative transport system based on BUSDUCT" is discussed. Assumptions regarding the construction of the locomotive and the production of nitrogen from the air for inerting purposes are discussed in the first part, whereas in the second part adapting thecurrent collector’s brushes to nitrogen injection, the relevant CFD calculations, the stand for testing the inertization, are presented. Many interesting experiments on the effectiveness of inertization using explosive mixtures of hydrogen and air are illustrated, described and discussed.
