説明

It is said that Hosokura Mine was discovered about 1, 100 years ago. At present it is operated under Hosokura Mining Co., Ltd., a subsidiary of Mitsubishi Metal Corp.<BR>The production of crude are of Hosokura Mine reached its peak of 75, 000 ton/month in 1970, but now it is reduced to 33, 000 ton/month.<BR>In former days only some parts of vein mostly consisted of galena were mined with over hand stripping method, and then shrinkage stoping method took the place of it. In 1957 sand slime cut and fill stoping method was introduced, because the stoping condition got worse according to the deeper working face. Further sand slime cut and fill descensional stoping method artificial roof of cement mortar has been adopted since 1975 in order to stope the are in weak rocks. Nowadays it is a main stoping method in this mine.
