Abstract

Für den Einsatz im untertägigen Berg- und Tunnelbau ist eine aus Bändchen 11, 12, 13, 14 bestehende Gewebebahn vorgesehen, wobei es elektrisch leitende und elektrisch nicht leitende Bändchen 11, 12 und 13, 14 gibt, die aber alle durch Eindispergieren von feuerhemmend wirkenden Substanzen und durch vor allem nichtmetallische, mikrokristalline, ein elektrisch leitendes Netz ergebende Nadeln 24, 25, 26 dauerhaft flammhemmend und dauerhaft antistatisch ausgebildet sind. Dadurch sind sie für den untertägigen Bergbau insbesonder geeignet.
