The system is used to track containers and materials during the entire transport chain from
the container loading position on the surface to the active underground workings.
After commissioning the ordered material in the SAP system, the material is loaded into
transportation units (containers) on the above ground loading area. For each material commission barcode labels are printed by the SAP system which during loading process the loader
attaches to the containers. Each material commission in the container is identified by such a
label which can be electronically identified by an individual barcode. If multiple material commissions are loaded into the same container, multiple labels are placed on the container side.
At the same time all containers are equipped with two passive long range RFID tags on
either side of each container. Both material commission numbers and container RFID tag
numbers are known by the material handling database, see Figure 4.
After loading, the transportation units are pushed on a track through a small shack (“linking station”) before they arrive at the shaft, Figure 5. Inside the linking station, an RFID
reader detects the container tag. Thus the stored container number and the container type
are known. At the same time, a barcode reader records the barcode label on the container,
which indicates the commission number. Thereby the information on material content, commission and transportation unit are fitted together (linked) and thus the content and destination of each transportation unit are known. Next time, each transportation unit is detected
via RFID at the shaft entrance before being lifted down to the mine. Another RFID reader
at the shaft exit detects the containers returning from the underground installations. AnaFigure 4. Material Label and RFID tag on the container.
