条带式矿柱嗣后充填采矿方法在缓倾斜磷矿开采中的应用

Application of strip pillar subsequent back-filling mining method in mining of gently inclined phosphate rock

根据湖北杨柳磷矿区的开采技术条件,将普通空场房柱法和条带式矿柱嗣后充填采矿方法进行了对比分析,发现条带式矿柱嗣后充填采矿方法既能保证采矿的安全,又可以提高矿石的回采率,是一种较为适合缓倾斜中厚矿体开采的新方法。

Comparative analysis of common open-stope mining method and strip pillar subsequent back-filling mining method in light of the mining conditions of Yangliu phosphate mining area in Hubei showed that the strip pillar subsequent back-filling mining method could ensure safety in mining operation and improve the ore recovery rate as well and is considered as a new method suit- able for mining gently inclined medium thick ore body.
