POTENTIAL ASSESSMENT AND ENVIRONMENTAL BENEFIT ANALYSIS OF SHALLOW GEOTHERMAL ENERGY IN THE URBAN PLANNING AREA OF XUZHOU, JIANGSU PROVINCE

Shallow geotherm is a kind of clean, safe and renewable energy. The urban planning area of Xuzhou City, Jiangsu Province, covers a total area of 3157km², including 641km² of downtown area. Based on the hydrogeological and engineering geological drilling, thermal property test and thermal response test in the planning area, this paper recognizes the geological background, forming conditions, distribution and geothermal field characteristics, and divides the suitability zones for exploitation and utilization of shallow geothermal energy, then evaluates the resources potential and analyzes the environmental benefits. The results show that the energy saving and pollution reduction effect is considerable.
