Abstract

The mining method of the deep slowly inclined-thin to medium thick-soft interlayer ore body is of No.6 pit in Jingning phosphate mine of Yunnan Phosphate Chemical Group Co.,LTD., has been studied, though the research techniques of field investigation, theoretical analysis and scheme comparison, on basis of the comprehensive analysis of the occurrence characteristics of ore body mining engineering, the technical conditions and the bottom characteristics of surrounding rock. The results show that:(1)the mixed mining way of seam, 1 seam and 2 seam should been carried out, as the ore grade could reach 22.97% and the high resource recovery. (2) for the typical hard-to-mine ore body of No.6 pit in Jingning phosphate mine, it is very difficult to obtain the ideal economic and technical index by using a single mining method. The section shrinkage-caving method is the right one to take as the mining method to the hanging wall seam, and duo to the seam is thin, for the footwall seam, it should take shallow-hole shrinkage mining as the mining method. The related results provides certain reference for the mining way of the deep mining of Yunnan phosphate group corporation and similar conditions of open pit mining of phosphorus mine.
