14  The Neuberg tunnel


Stud Name:          "Neuberg - Stollen" as a new uphill climb below the

                                   Obernberg - Stollen, the later "Lipplesgraben - Stollen"

Struck:          1586                

Leave:                  1879   

Length:                         994 m  

Altitude:                    909 m

Emperor Rudolph II set up a commission to stop widespread abuses in the chamber property and to ensure the implementation of the provisions laid down in the Reformation - Libelle of 1563. Therefore, in 1586, a mountain inspection was carried out at the Ischler Salzberg. The mining inspection recommended, for the required increase in salt production, the opening of a new tunnel, the Neuberg tunnel.

Since the salt could be detected over the entire planned thickness of the mountain through the exploratory digging carried out by Archduke Matthias - tunnel, the tunneling of the Neuberg - tunnel began in 1586.

The Neuberg tunnel was already being considered in the north-facing steep terrain of the Mitterberg. This would have made the main shaft much shorter than when driving from the west. The construction of a 300 bar (357.6 m) long section in hard limestone, the difficulty of delivering timber and the construction of a slag heap in the steep terrain were important reasons for starting the exploration from the west. In addition, the required pit and pole wood could be delivered effortlessly from the Steinberg saw. It was also possible to connect inexpensively to the Strehn, which had already been built by Archduke Matthias to drain off the brine extracted in the Obernberg tunnel.    

In order to speed up the exploration work, in 1589 a counter-construction was initiated from a pit sunk from the Matthias tunnel. However, great difficulties were encountered with this opposing structure, which was located in water-bearing limestone. The tunneling came to a standstill when 160 rods (191.2m) still had to be driven to the point of breakthrough. In 1590 further driving of the opposite building was even supposed to be stopped, but the Ischl mountain championship successfully resisted this. Until the breakthrough, however, the inflowing water and the rock that had been thrown out had to be drawn up into the Archduke Mathias tunnel using a hand reel, which was expensive.

Situation of the Schöpfbaue in the Neuberg tunnel around 1654:

A total of 11 pumping stations;                                                                                                                                              

Eder, Wildenhofer, Wolkenstainer, Daniman, Preuner, Wangner, Hintersteiner, Rossner, Urschenbeck, Lichensteiner and  Mondseer  or Manser - construction. In the continuation of the Neuberg tunnel - main shaft there were 11 burrows.  As early as 1648, the Eder, Wildenhofer, Wolkensteiner, Daniman and Preuner buildings were united under one sky and had 22 rooms (2,490.4m³) of brine content, 11 bars (13.2m) down to the sole of the Neuberg - stollen to dry up. The cut burrows were driven under with a weir furnace in the Frauenholz tunnel, could be emptied via a discharge dam and were referred to as Graf Preuner weir.   

The Wagner and Hintersteiner buildings were also under the same sky, were prepared for an outlet weir and then combined with the five previous buildings in the Preuner and Raßfeldner weirs.

The Roßner - Bau also united with the mentioned buildings in the Preuner and Raßfelner - weir.

In 1730 the Graf Preuner weir broke through to the Rassfelner weir in the Frauenholz tunnel. After the now combined Preuner and Raßfellner weir had been provided with new dams in 1733 and new discharge boxes in 1734, it could now be leached up to the Matthias tunnel. To facilitate the cleaning, a cleaning pit was sunk from the Matthias tunnel. In 1744 the Preuner and Raßfellner weir had to be abandoned because it had come dangerously close to the overlying rock. The Preuner and Raßfellner weir then served for some time as an impact work for the Zierler weir located in the St. Johannes tunnel.

The Urschenbeck, Lichtensteiner and Mansen  The building also stood under one sky, contained 12 rooms (1,358.4 m³) of brine, and could be emptied as a weir with an outlet dam, the Klementen weir, through the Frauenholz tunnel. The Klementen weir was only watered down in the Neuberg horizon and left before 1800.

Behind the Manser building there was still a drainage pit down the Frauenholz tunnel.

The Neuberg tunnel – main shaft was also driven too far into the footing and had hit fresh water in the limestone air. After water ingress in 1641, a Lettendamm was built, the fresh water was collected and safely guided to the surface in wooden tubes.

In 1707, the Neuberg tunnel contained 11 barrages divided into three groups, which were still operated as 3 dam weirs, but not much was to be expected from them.

Situation of the weirs in the Neuberg tunnel around 1850:

A total of 4 weirs, all pronounced dead around 1850;                                                                                               

Seeauer -  Weir, Lang - weir, Klementen - weir, Paul Müller - weir.

In 1840 the first pit linings were carried out on the Ischler Salzberg in the Ritschner - conversion of the Neuberg - tunnel.

Until 1933, the Albrechten conversion, the Ritschner conversion and the Schwind Schurf were kept open in the rear part of the Neuberg tunnel for the drainage path into the lower-lying horizons.
