摘　　要：焦家金矿寺庄矿区井下存在留矿法采矿形成的老空区,由于长时间未进行充填处理,导致部分塌落和回采附近矿体易形成安全隐患。该矿区通过少量下向天井工程与空区贯通施工,架设格筛进行回填大量掘进工程产生的废石,对空区进行干式回填,并在回填接顶时进行原留矿法顶柱矿石回收。该综合治理方法具有成本低、消耗掘进废石、可回收矿柱等优点,对中小型矿山老空区的综合治理具有借鉴价值。The underground of Sizhuang mining area exists old workings that was formed by mining method of past, because we cant take filling treatment method for old workings for long times, it lead to parts of general collapse and form hidden danger of orebody nearby mining. Through construction of a little under gap fill transfixion, erection of grizzly for backfilling lots of waste rock produced tunneling for workings, and recovery top pillar ore of primary shrinkage method as backfilling direction patio engineering and engineering, we make dry backroof contact. The comprehensive treatment method is advantage of low cost, consumption of tunneling waste rock, recovery ore pillar, and has reference value for old workings of similar middle-small mine.
