The objective of this study is to prove the long-term geoscientific stability of the geological environment. The survey will clarify the extent and degree of mechanical change influenced by fault movement deep underground as well as the surface. The study was conducted in Mozumi of the Kamioka mining district, located in the Atotsu active fault system zone. This year, a study was carried out by measuring stress state and rock properties around the active fault. At first, stress measurement by double fracturing was conducted at Nagato No.1 borehole in order to compare a newly measured stress state with the one done last year. The difference between them was very little. Secondly, the first stress measurement was carried out on the Nagato No.3 borehole.

The objective of this study is to prove the long-term geoscientific stability of a geological environment. This was accomplished by measurement of stress and study of rock properties around an active fault in the Atotsu fault system near Mozumi in the Kamioka mining district. A future goal of the project is to clarify the areal extent and degree to which fault movement at the surface and at depth affects mechanical changes.

The objective of this study is to prove a long-term geoscientific stability of geological environment by means of measuring stress state and rock property around the active fault in order to investigate geological environment influenced by fault movement in underground as well as surface. The study was conducted in Mozumi mine of the Kamioka mining district, located in the Atotsu active faults system zone.
