金属价格低给瑞典布利登矿物公司的矿山带来了极大压力,由于该公司大部分矿山都是开采多金属、低品位贱金属硫化矿物,所以要不断地提高生产效率。北加潘贝里矿(Garpenberg Norm mine)位于斯德哥尔摩西北150km、加潘贝里矿(Garpenberg mine)和选矿厂东北4km处,该选矿厂也处理北加潘贝里矿的矿石。布利登公司1987年在该矿将用分层充填采矿法从地下矿采出 The low metal prices put tremendous pressure on the mines in Bredden, Sweden, and most of the company’s mines are producing polymetallic, low-grade base metal sulphide minerals, thus continuously increasing their production efficiency. The Garpenberg Norm mine is located 150km northwest of Stockholm, at the Garpenberg mine and 4km northeast of the concentrator, which also processes the ore from the North Garpambelli mine. Briden company in 1987 in the mine will be stratified filling mining method from underground mining
