Tracking in Mines: RTLS in underground or open pit mining

Digitalization in mines for optimizing processes. Whether it is the mining of near-surface raw materials such as stone, sand or gold in an open pit mine or the extraction of minerals, metals or ores underground, documenting the entire production process and communication is a challenge for most mining companies. Often, everything is documented using paper notes or forms.
