Based on a graphical representation of the measurement results, a drilling plan was drawn up together with Klaus Löcker from Prof. Neubauer’s team, the implementation of which should lead to clarification of “the underground conditions”. Volker Wendt’s drilling company from Hesse was busy for a week to achieve this clarity. In some cases we succeeded, the work was successful. On one occasion, for example, a gallery was cut, as the subsequent analysis of the images from the camera inspection of a borehole proves. It was probably the main gallery of the mine. In another case, structures could be seen that indicate human intervention that would fit into a shaft. Unfortunately, the work could not be continued for financial reasons.
