Extraction system for mineral extraction and retaining device for a sensor system therefor

摘要

The invention relates to an extraction system for mineral extraction, having a machine frame (11) movable along a supply device, said machine frame having detaching tools (14, 15) for the material to be extracted for each travel direction on the front side (13) thereof when in operation facing a working face, and having a sensor system for recognizing mineral host rock disposed on the machine frame (11). In order to create an extraction device that may be used or provided with an improved sensor system, a retaining box (20) for the sensor device is attached in a projecting manner on the front side (13) of the machine frame (11), wherein a georadar is preferably disposed in the retaining box (20) as a sensor system.
