摘　　要：某磷矿缓倾斜薄矿体,部分围岩稳固性较差。为探讨该矿的采矿方法,通过对影响采矿方法选择的主要因素的分析,提出采用房柱法采矿嗣后充填法和进路回采充填法,对采矿方法的采场布置、采切工程、回采工艺进行了论述。选择的采矿方法对该矿山采矿生产具有指导意义,也可应用于相似地质条件的矿山。The stability of some surrounding rocks in a gently inclined thin ore body of a phosphate mine is poor.In order to discuss the mining method of this mine,through the analysis of the main factors affecting the selection of mining method,the room and pillar subsequent filling method and upward drift filling method are proposed.The stope layout,mining engineering and mining technology of the mining methods are discussed.The selected mining method has guiding significance for the mining production of this mine,and can also be applied to mines with similar geological conditions.
