Analysis and modification of the ventilation network of an underground tourist mining facility in order to make new workings accessible

Abstract

The attractiveness of tourist facilities is based, among other things, on the continuous expansion of their offer. In the case of the underground mining facility, this will involve making new workings available for tours. To this end, analyses were carried out on the existing ventilation network, a model of the network was made and adapted to the future situation. In order to ventilate the new excavations, a new fan station, and a large diameter borehole were designed. Phases Ia, Ib, II and III of the changes to the ventilation network with a view to opening up a new chamber are presented.
