Abstract
Streaming potential method has been applied in the Kamaishi Mine. In FY 1995, self-potential (SP) was monitored on the wall of gallery by varying the pressure in the well with open/close operation of the mouth of well having spring water, which was drilled from the gallery. It was confirmed that SP changes remarkably at the wall having a great number of fractures with spring water. It was considered that the change in SP is due to the streaming potential generated by the flowing underground water from the gallery side to the fractures in the well. In this paper, this continuity of the wall of gallery and the fractures in the well is estimated. In the present tests, SP changes were observed at walls of surrounding galleries by varying the pressure in the well with open/close operation of the mouth of borehole at various drilling depths during drilling of borehole. As a result, SP changes were observed at the wall of gallery when reaching to the depth with increased spring water. The results agreed well with the test results conducted at the same field in FY 1995. It was confirmed that the streaming potential method is a useful method for grasping
