Study on the Mechanical Properties of Coarse-grained and Fine-grained Granite Under High Temperature

The real development of hot dry rock(HDR) geothermal is deep HDR geothermal. Because of different diagenesis environments, the mineral composition and micro-structure of deep granite are quite different from those of shallow granite. To reveal the real characteristics of deep granite and guide HDR geothermal development, the difference of thermal and mechanical properties between the granite in Luya Mountain, Shanxi Province, China(coarse-grained granite) and the granite in Shandong Province, Chi...
