桃冲铁矿低贫化放矿工艺的应用

Application of the Low-dilution Ore Drawing Technology in Taochong Iron Mine

为解决无底柱崩落采矿法低贫化放矿工艺实施存在的问题，开展了低贫化放矿工艺的应用途径的分析与试验，提出了对矿山正常生产影响最小的全矿整体过渡的实施方式，应用较为成功。

To solve the problem in adopting the low-dilution ore drawing technology in the block caving mining,the analysis and the experiment of its application approach were made and a complementing mode of whole-mine integral transition which could have the least influence on the routine operation of the mine was suggested and has been applied successfully.
