Thermal conductivity and heat withdrawal performance — thermal conductivity water-saturated

This application is intended to provide the builders, planners and drilling companies with geological, hydrogeological and geothermal data for the design and construction of geothermal probes. The following maps can only serve as orientation, as the underlying drill grid does not allow reliable, area-like statements due to the complex geological storage conditions in wide areas. The design of the required drilling depths must therefore always be based on the layer sequence encountered during the drilling. The data for the loosening rocks come from the VDI 4640. The values for the solid rocks were determined in the State Office for Geology and Mining. Terms of use see: http://www.lgb-rlp.de/karten-und-produkte/online-karten/nutzungsbedingungen-fuer-online-karten.html:Die layer directories of more than 1500 nationwide and at least 100 m deep drilling were evaluated. The layers were assigned thermal conductivity for the dry and water-saturated state. For the loose rocks, these correspond to the VDI 4640 sheet 1. The thermal conductivity of the solid rocks are mean values based on studies at the State Office of Geology and Mining. These values were used for depth intervals 40, 60, 80 and 100 m.
