1. A method for a zone passage control system for an underground worksite having a plurality of operation zones for autonomously operating mobile vehicle operations, the method comprising:
associating a first passage control unit with a first zone and a second zone of the underground worksite, the first passage control unit separating the first zone and the second zone;
detecting state parameter information of the first zone and the second zone;
merging the first zone and the second zone into a fusion zone on the basis of the state parameter information of the first zone and the second zone; and
adapting the zone passage control system to allow a first autonomously operating mobile vehicle to pass the first passage control unit in the fusion zone without interrupting operation of a second autonomously operating mobile vehicle in the first zone and/or the second zone.
