GAS EMISSION AND GAS UTILISATION IN THE ABANDONED MINING AREA OF THE RUHR DISTRICT

摘要: As in other coal mining areas of Europe also the Ruhr district problems with gas outflows on surface may occur, when mines are closed and ventilation system is shut down. The volume, which remains measures abandoned area, causes diffuse inflows surface. This depends permeabilities remaining roadway system, filled shafts rock layers, both area outside it. safety their control described concrete examples. However mine an energy source utilisation supported Germany by a new law since year 2000. exhausted utilized at ten locations moment (electrical power so far about 39 MW). For example location Kurl explained more detail. Further development schemes, especially boreholes, intended.
