摘　　要：为解决留矿法采后形成的采空区处理和间柱回收问题,保障后续生产的安全和间柱资源的回收,本文结合盘龙铅锌矿采空区和矿柱的赋存条件,确定了现有空区的处理方式必须采用充填法处理,仅在独立的小采空区采用封闭空区的处理方法。同时对比分析了三种不同的间柱回采方法,通过优缺点比较最终选择上向水平分层充填采矿法作为间柱回采的主要方法。In order to solve the problem of the treatment of the mined out area and the recycling problem of the pillar,to ensure the safety of the follow up production and the recycle condition of the pillar, this paper based on the occurrence conditions of the PanLong lead-zinc mine goals and pillar, filling method for treatment of mined out area was been selected, the treatment method of closed space is used only in the small goals. At the same time, the analysis of three kinds of different pillar extraction methods shows the final selection of the horizontal slicing and filling mining method is the ultimate choice.
