为寻求一种适合于贵州开阳磷矿矿体赋存条件的采矿方法,解决开阳磷矿现行采矿方法存在的生产安全差、损失贫化大、效率低等问题,实现优质资源充分合理利用,采出的磷矿石可直接用于加工高浓度磷肥,由贵州开阳磷矿矿务局、化工部化工矿山设计研究院、法国索法明公司共同承担的采矿方法工业性试验取得了成果,并于1989年4月4日通过了专家鉴定。开阳磷矿矿务局青菜冲矿缓倾斜、倾斜矿体地下采矿方法工业性试验研究,属国家重点科技攻关项目。自1985年7月1月试验采区开拓工程开始施工至1988年8月完成试验考核,历时38个月,园
In order to find a suitable mining method for the occurrence of Kaiyang Phosphate orebody in Guizhou Province, the existing mining methods of Kaiyang Phosphorus should be solved, such as poor production safety, large loss and poor efficiency, low efficiency and other problems, so as to realize the rational and rational utilization of high quality resources , Mining of phosphate rock can be used directly for the processing of high concentrations of phosphate fertilizer, Kaiyang Phosphate Mining Bureau of Guizhou Province, Ministry of Chemical Industry Mining Design and Research Institute, France Fasame company shared mining industry test results , And on April 4, 1989 passed the expert appraisal. Kaiyang Phosphate Mine Bureau of Greenschizizhuang slow inclined, inclined orebody underground mining methods industrial test research, is a national key scientific and technological projects. Since July 1985, the trial mining area development project started construction to August 1988 to complete the test assessment, which lasted 38 months, Park
