倾斜脉状薄矿体开采方法的研究

Study of mining method for inclined thin vein in a copper ore mine

某铜矿在矿区南部探边扫盲时 ,探获了与原主矿体赋存状态截然不同的倾斜薄矿脉 ;其产状变化大 ,开采条件较复杂。根据矿脉地质条件的不同 ,探讨了改进型的采矿方法 ,即房柱全面矿块空场采矿法和分段空场留矿法 ,并获满意效果。该采矿方法的成功应用 ,将对该矿山或同类倾斜薄矿脉的开采具有一定的指导意义。

Through an exploratory survey of residual deposit in the sourthern zone of a copper ore mine,inclined thin veins with difficult occurrence and complicated mining conditions were discovered.To exploit these veins,improved methods of pillar-and-room full-advanced open-stope mining and sublevel open stope & shrinkage mining have been tested with satisfactory results.These improved mining methods can be taken by simillar mines for reference.
