抄録

At the Yanahara Mine, a huge are body has been discovered in the depth of 400m, as a result of the systematic prospecting from underground and surface.<BR>But unfortunately on the surface, there is the river Yoshii, one of the three largest rivers in Okayama prefecture, this may cause the mine water to increase gradually as development progress. In addition, mine water must be entirely pumped up from the bottom of the are body several hundred meters below the surface, and the water flowing down through the goof is highly oxidized, so that the neutralizing treatment of this water is very expensive. Besides there may be a danger of mine inundations due to an unexpected underground flood like Kawarayamuki explorative drift, where the flood about 8m3/min happend in April, 1960.<BR>It is very important to find the source of the mine water and to prevent the mine inundations. For this purpose, we have researched into the water problem for these several years, though we cannot get any conclusion yet.
