This paper reports on the first large-scale project in the U.S. for utilizing water from abandoned mines for geothermal applications. This project proved the high potential of turning water in deep abandoned mines into a renewable energy resource, which is safer, greener, and more abundant than other conventional low-enthalpy geothermal applications. In this paper, a real demonstration project …
The exploitation of geothermal energy could cause additional thermal load imposed to the foundation and surrounding soils. The effects of temperature changes on the response of energy piles which can induce thermal expansion and contraction of both piles and soils need to be examined. This study investigated the behaviors of an energy pile and the surrounding soil using the model test and 2D …
