Abstract

Disclosed is a device intended to reduce the danger of inflammability during the operation of a partial-cut tunnelling machine, the device having nozzles designed to eject air and/or an air/water mixtures. The device includes a cutter arm (3) on which the nozzles are mounted with their output axes (11) oriented so that the jets impact the heap of debris lying in front of the loading device (7).
