METHOD FOR LOCATING PERSONS AND/OR MOBILE MACHINES IN MINE CAVERNS USING RFID TECHNOLOGY, AND LONGWALL FACE EXTRACTION INSTALLATION FOR CARRYING OUT THE METHOD

摘要

The invention relates to a method and a longwall face extraction installation having a device for locating persons and/or mobile machines in mine caverns using RFID technology, with a plurality of base stations (20) which are arranged in a distributed manner along the mine cavern to be monitored and have a transmitter and preferably a receiver, with at least one RFID transponder (12) which is associated with the person or machine to be located, has stored identification data, can be activated using the base station (20) and can be read in a contactless manner using the base station (20). In order to provide a method for locating persons and a longwall face extraction installation, in particular for coal mining, which make it possible to effectively use RFID technology, the transmitters at least of adjacently positioned base stations (20) along a region of the mine cavern to be monitored successively emit their transmission wave (21") in order to activate an RFID transponder (12).
