This includes exploration and Safety work may also be necessary, as there are several coal seams on the upper edge of the carbon in the property area, which are at least partially assigned to impact classes 1 and 2 and were therefore most likely mined during the day. To increase school capacity now an extension to the existing school building will be carried out. For this purpose, exploratory drilling must be carried out to determine whether the remains of this old mining industry are relevant to the construction project. For this purpose, exploratory drillings are advertised as full crown drillings (Part A). Only after it is available Based on the results of the exploration, a decision will be made about the further course of action and any necessary security measures.
