摘　　要：对于不稳固围岩的急倾斜薄矿体 ,通常采用矿块分矿房、矿柱二步骤回采 ,不仅贫化、损失较大 ,而且第二步的回采亦不安全。本试验研究为此提出了矿块一步骤上向分层胶结块石柱与干式充填组合的回采工艺 ,并经实践证实具有较好的经济效益和社会效益。Two step mining with ore block divided into stope and pillar is normally used for steep-dipping narrow veins with unstable country rock.This method results not only in more dilution and loss of ore but also in unsafty for the second stop mining.For this reason,our research set up a mining technology which got ore block mined in a step with the combination of upward slicing cemented lumpy-rock columns and dry filling,and it was proved in practice that this technology can provide with good economic and social benefits.
