Modeling potential impact of geothermal energy extraction from the 1B Hydraulic System of the Sydney Coalfield, Nova Scotia, Canada

摘要

To predict the hydrogeochemical stability of the 1B Hydraulic System of the Sydney Coalfield in Nova Scotia, we are simulating the behavior of groundwater flow and pollution transport using FEFLOW. In order to utilize mine water for geothermal energy extraction, predicating alterations in thermal dynamics is of concern. The simulation considered effects of pumping water from a lower depth and re-injecting into higher depths as well as the change in temperature of the water after energy extraction. This paper presents our preliminary results simulating the potential impact of the geothermal energy extraction on the behavior of groundwater flow and pollution transport.
