摘要
保安矿柱是露天转地下开采重要的工程实施。以富家矿露天坑底保安矿柱为工程背景,详细介绍了应用下向水平进路高水基胶结充填采矿法和机械化下向倾斜进路粗骨料胶结充填采矿法回采保安矿柱的工艺工程。工程实践不仅取得了可观的经济及社会效益,还为其他矿山类似工程提供了宝贵的经验。
Safety pillars are an important part of the construction work needed in the transformation of a mine from open pit mining to underground mining .The paper takes Fujia mine for engineering background ,and in detail intro-duces the application of downward high water base cement filling method with horizontal access and mechanized down -ward coarse aggregate cement filling method with inclined access to recover safety pillars .The engineering practice not only achieves considerable economical and social profits ,but also provides valuable experience for similar mines .
