Rock formation up to 100 m depth

The map gives indications of the expected up to 100 m depth of rock sequence, divided into solid rocks, loose rocks, karst rocks, loose rocks over fixed rocks etc.. The basis for the classification is the 1:200,000 scale geological map (Guek 200) This information provides an initial information on which drilling method is suitable for the respective plant location. For example, in looser rocks such as sand and gravel, a so-called rinse drilling process is used. In solid rocks such as limestones, granite, etc., a hammer chisel drilling process is used. The data set provides a basis for large-scale considerations and does not replace the conduct of detailed investigations.
