The active fault survey tunnel across the Mozumi-Sukenobu Fault is located at the Kamioka Mine, northern Gifu prefecture, Central Japan. At present, the comprehensive studies of the active fault are being carried out in this tunnel. In this report, the results of the laboratory test using steel pipes and numerical simulation for the new ground stress measuring instrument were presented in order to inspect the stress state around the active fault.

The active fault study drift that crossed the Mozumi-Sukenobu fault (a member of the Atotsugawa fault system) is located at the Kamioka mine, northern Gifu prefecture, Central Japan. The comprehensive study of the active fault is done in this drift. The purpose of this investigation is to obtain the data of the basis to clear the hydro-geological structure around the active fault. From December 1, 1997 to March 13, 1998, the pore pressure was measured using the hole.

The active fault survey tunnel that crossed the Mozumi-Sukenobu fault (MSF) is located at the Kamioka mine, northern Gifu prefecture, Central Japan. The comprehensive study of the active fault, such as the study of the earthquake mechanism and the development of the new initial stress measurement method is done by using this tunnel. One of the purposes of this investigation is to define the three-dimensional distribution of the MSF by geological survey, on the basis of the seismic and geophysical studies on this fault. The other purpose is to develop the new initial stress measurement method.

The active fault survey tunnel that crossed the Mozumi-Sukenobu fault (a member of the Atotsugawa fault system) is located at the Kamioka mine, northern Gifu prefecture, Central Japan. The comprehensive study of the active fault is done by using this tunnel. The purpose of this investigation is to define the hydrological characteristics of the Mozumi-Sukenobu fault crush zones. The permeability of the crush zones is measured by the Lugeon test and the simple injection test.

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.
