摘要
介绍了潘洛铁矿采取坑内掘进废石内排、选矿抛废回填等充填井下采空区措施,提高了主井出矿能力、减少了征用土地、消除了安全隐患,取得了明显的经济效益。
In Panluo Iron Ore Underground Mine, the method of using inner-disposal of waste rock from drivage and using railings from beneficiation to back fill goals is adopted. The method has achieved remarkable profits such as increment of ore output lifted by main shaft, reducing of occupation of land, elimination of hidden dangers.
