Title Ventilation of the working face during mechanised part-face driving
Original title Bewetterung des Ortsbereichs in Teilschnittmaschinen-Vortrieben [in German]
Bibliographic information 1984, Vol.120, No.15, p.967-976. Illus. 13 ref.
Abstract Results of and conclusions from tests of ventilation conditions in 129 mechanised driving sites: face ventilation during cutting, free-jet face ventilation from a main ventilation line or from an auxiliary line, ventilation of the working area during cutting, ventilation of the overlap area between the auxiliary ventilation and the dust collectors. Empirical relations allow the calculation of distances and the speed at the air outlet in such a way that air speed at the working face does not drop below a certain level. New devices (such as a diaphragm to regulate the opening of the air outlet) that enable higher air speeds and more favourable climatic conditions to be obtained without interfering with dust collection.
