[S-MP44] Dynamics of melt, ductile and brittle rock mass and energy system
Wed. May 25, 2016 1:45 PM - 3:15 PM 301A (3F)
Convener:*Noriyoshi Tsuchiya(Graduate School of Environmental Studies, Tohoku University), Hiroshi Asanuma(AIST), Yasuo Ogawa(Volcanic Fluid Research Center Tokyo Institute of Technology), Shigemi Naganawa(The University of Tokyo), Chair:Masaoki Uno(Graduate School of Environmental Studies, Tohoku University)
Nature of rock mass below the brittle-ductile transition (BDT) is of great scientific interest to understand various phenomenon in the earth's crust. We will review and discuss current understanding of characteristics the rock mass below the BDT, including composites, stress, failure mechanism induced by liquid injection and associates earthquake generation mechanism, and water rock interaction, considering engineered geothermal development in the BDT. Discussions on the possible phenomena in the geothermal development in the BDT will be followed in this session.
New drilling technology is key of issues. This session will cover advanced drilling technology under high temperature conditions for energy extraction.
