Assessment of hazardous gas emission to the surface over former mined areas

Description: Das Projekt "Assessment of hazardous gas emission to the surface over former mined areas" wird vom Umweltbundesamt gefördert und von Universität Stuttgart, Institut für Wasserbau durchgeführt. The numerical model MUFTE-UG which is capable to simulate two-phase, gas and water, flow processes in the subsurface has been adapted to the special conditions of methane gas problem. Several simplified test cases have been carried out to determine sensitive parameters depending on the geological structures. For the next period, two things are planned in a close cooperation with DMT. On the one hand, a 3D model of an existing coal mining area will be built up and prepared for the numerical simulation. This requires the collection of available data, their integration into a CAD system (see fig. 2, two cuts through a coal mining area in the Ruhrgebiet, Germany), a data base and a mesh generator. On the other hand, the influence of fractures, fracture-networks and small scale heterogeneities on the methane migration processes will be investigated.
