Realized. In order to develop a new mining field, it is necessary to establish a connecting line between the shaft and the weather shaft of the mine. In addition to the actual route access, the production is different
Cross sections and route crossings are part of the order. In the most difficult geology, more than 3,000 m of the connecting line with a cross section of the route

in installation thicknesses between 5 and 20 cm. These depend on the

Completed after removing the head. Mountain anchors are installed in addition to the shotcrete to minimize convergence. As a result, the convergences that have so far occurred in the heavily broken and irregular mountains
In contrast to the track areas, which were previously with the

poor quality characteristics, supply of materials from local suppliers
established. A further substitution of German deliveries with local solutions is currently being examined. Problems arise again and again, the disproportionately high coordination effort of the processes and
both on the technical side and in planning and billing.
The differences in mentality, culture and basic economic system do not make everyday project work easier.
