Methane hydrates, which form at low temperature and high pressure, are found in ocean sediments and being evaluated as a potential fuel for the future. The worldwide total of methane hydrate is estimated to be equivalent to 250 trillion cubic meters of methane gas. In order to establish an efficient production technology for extraction of methane from hydrates, deformation and movement behaviour of ocean sediments have to be basically clarified. The aim of this study is to develop the low temperature auto-controlled triaxial compression apparatus and to estimate the mechanical properties by using the ice rock matrix specimen. The preliminary results on relationships between deformation properties, shear strength and sand content in the specimen are presented and discussed.
