Shotcreting is currently underway in the south research access tunnel 500 m underground at Mizunami Underground Research Laboratory. The use of the low alkaline super shotcrete spraying method, which makes it possible to obtain high strength and high stiffness quickly after spraying while minimizing an environmental impact, is being considered as a means of stabilizing an excavated rock surface whose condition is rapidly deteriorating. For the purpose of evaluating the applicability of the method to the shotcreting work currently in progress, a verification field test was conducted. This paper briefly reports on the test.

As part of environmental remediation of Ningyo-toge Uranium Mine, multi-layered capping is constructed to reduce rainwater infiltration at the upstream of the Mill Tailings Pond. Settlement is expected due to consolidation characteristics of mill tailings and clayish sediments which exist below capping. Numerical simulation is carried out to expect the settlement amount during and after the capping construction. Settlement amount has been measured periodically, and the simulation result and measurement data are compared to evaluate the simulation method.

In this study, with the goal of applicability an in-situ measurement technique for monitoring generation and extension of the unsaturated zone around a drift, a set of water content measurement was carried out for the core samples collected during the excavation of pilot survey drift in a sedimentary rock formation. For the drill core collected under brine environment the Horonobe deep underground laboratory, FDR-V method was applied. FDR-V measures complex permittivity from reflection characteristic in the coaxial cable tip using an electromagnetic wave with high frequency. The results showed that the effects of the salinity on the measurement were insignificant.
