Global Circulation System
Projects such as the development of submarine hydrothermal deposits and high-level radioactive waste geological disposal are underway as geosphere development in extreme environments (deep sea, ultra-deep underground). For example, in the development of submarine hydrothermal deposits, we are investigating optimal development systems (such as excavation machine selection and pumping systems).
In order to improve efficiency, various elemental technologies (excavation and support of rock) have been developed and systematized.
The systems that catches the precursory phenomenon of rock mass failure and notifies the failure are developing. We are studying measures for environmental conservation (slope collapse, water quality deterioration, landscape considerations, etc.) at mining sites.
