A mine cage closure for closing the open front ends of cages generally consists of a curtain of flexible material penetrated at regular distances by horizontally running and laterally guided transverse elements. Without restricting the cross-section of the front end, the automatically operable and easy-to-install curtain 1 is provided with a drive 4, arranged in the deck roof 3, and tension means 5, which can be acted upon via the drive 4 and, deflected and guided via rollers 6; 20, are connected to the uppermost transverse element 7, the ends of the transverse elements 7 running in perpendicular, slot-like guides 9 located in front of the side walls 8. <IMAGE>
