- Abstract
Taking the east mining area of sixth pit of Jinning phosphate rock of the largest open-air phosphate mining company of Yunnan Phosphate Chemical Group Co., LTD. (YPCG) as engineering background, the study of the mining technology of filling method of gently inclined and thin to medium thickness phosphate ore-body with soft interlayer has been done, according to the the actual technical and economic conditions of the phosphate mine, on basis of the comprehensive research method of field investigation, theory analysis and engineering analogy. The results showed that: For the two layers of ore body containing soft interlayer, slicing techniques should be used to achieve high resource recovery. Meanwhile, it could obtain good economic results that the high concentration paste-like slurry which was made from a mix of waste rocks, dinas, cement and water has been conveyed to the underground working face by the ground pumping pipes. Related research could provide technical and theoretical guidance for the underground mining engineering construction of Yunnan Phosphate Chemical Group Co., LTD. and a large number of similar occurrence conditions of phosphate mines whicih surrounding the area of Yunnan Dianchi Lake.
