Abstract
The Toyoha Mine is operated under extremely high rock temperature. The geothermal heat is 10 to 20 times more active than the average of the Japanese Islands. The highest temperature ever observed in exploration drill holes is 242°C that must be equivalent to those of the geothermal fluids utilized for power generation in Japan. In order to improve the underground climate, the mine has a plan to introduce paste backfilling and to effectively reduce the heat flows from the mined out stopes. The surface flow test was carried and the second test is being arranged in underground.
