THIS PAPER WAS PRESENTED AT A TECHNICAL SEMINAR OF THE MINING SECTION OF THE "SOCIETE DE L'INDUSTRIE MINERALE", CAEN, 12-13TH MAY, 1976. THE AUTHOR EXAMINES THE CONSTRUCTION OF GOOD-QUALITY TRACKS ON THE FLOORS OF POTASH MINES; THE CONSTRUCTION COMPRISES THE FOLLOWING STAGES: A GOOD TRANSVERSE SURFACE DRESSING, THE BEST LONGITUDINAL LEVELLING COMPATIBLE WITH THE UNDULATIONS OF THE LAYERS, REDUCTION IN THE SUPER-ELEVATION TO AN ACCEPTABLE LEVEL (APPROXIMATELY 6 DEG MAXIMUM). A SPECIAL MACHINE IS DESCRIBED, WHICH HAS BEEN DESIGNED FOR THE ECONOMICAL CONSTRUCTION OF TRACKS.
