Abstract
this paper introduced current production status of a fluorite mine, aimed at the disadvantages of original design which was three-level blind slope;the mine was converted into blind shaft process. Based on actual operation practice, although the working of shaft developing was more than slope developing, but ore lifting avoiding repeated loading and unloading of loaders;loaders directly lifted from mine bottom up to the mine adit, greatly enhancing the efficiency operation, and reduced 269100 RMB cost each year for the mine.关键词
