Abstract
The ore body of this mine is flat with an average dip of 12°and its thickness is large running as thick as 4 meters on the average and with a maximum of 25m. However, its inclination is highly variable not only in the dip side but also in the strikeside. Moreover, pyrrhotite which forms the principal component of the ore is extremely unstable and, naturally, we have to make use of a large number of scrapers to mine the ore in a short space of time. Mining is done by room and pillar method but in certain faces, tests are being made with sand mortar filling.with band pillar system in order to stope out ore pillars.
