点柱留矿法在潘洛铁矿的试验应用

Experimental Application of Point Pillar Shrinkage Method in Panluo Iron Mine

潘洛铁矿属中型生产规模铁矿山，原设计分条分段崩落法在生产中存在较多问题。针对矿体赋存的地质条件和特点，研究决定将原方法改为点柱浅孔留矿和留矿全面法，试验效果良好。这里介绍点柱留矿法的试验应用情况。

Panluo Iron Mine is of medium size and there are many problems in its production which uses the originally designed sublevel caving in strips.In view of the geological conditions and characteristics of ore occurrence,it was decided to replace the original method by point pillar shallowhole shrinkage method and shrinkage breast method.The test has achieved good results and the experimental application of point pillar shrinkage method is described.
