摘　　要：无底柱分段崩落法放顶工程量大,成本费用高,是困扰崩落法矿山的共同问题。以某高分段崩落法矿山为背景,在综合分析传统人工强制放顶方法的基础上,研究提出了第一分段边回采边放顶方法,通过技术经济指标和优缺点对比,推荐矿山采用第一分段边回采边放顶方法。该方法直接在第一分段凿岩巷施工放顶炮孔,不需要新增放顶工程,实现了回采与放顶的良好结合,节省放顶成本60%,放顶效果良好,可在类似矿山推广应用。The roof caving for non-pillar sublevel caving meth- od with large engineering and high cost, is a common problem for caving mining. Taking a high sublevel caving mining method in one mine as the background, based on the comprehensive analysis of the traditional artificial caving method, the first sublevel mining and caving method was put forward. Through comparing the technical and economic indexes, as well as the advantages and disadvantages, the first sublevel mining and caving method was recommended. The new method directly drilled blasting holes in the first sublevel roadway, without roof caving engineering. Achieving a good combination of mining and caving, reducing the roof caving cost by 60%, and obtaining good effect of roof caving, the new method can be proposed in similar mines.
