Thermal and mechanical properties of fracture-filled granite with different structural forms under high temperature and high pressure

Meitan xuebao
The reservoir of deep hot dry rock (HDR) geothermal energy is not intact rock mass, which includes a large number of fractures induced by geological tectonic movement. The tectonic fractures are subsequently filled by hydrothermal fluid.
