摘　　要：阐述了缓倾斜极薄矿体面临的技术现状,并针对某铜矿现有房柱式堑沟削壁充填法的采矿方法缓损失贫化大,作业条件差,生产效率低等特点,采用长壁分条、堑沟削壁、移架放顶全面采矿法,从支护方式、凿岩工具等技术方面进行创新,解决了某矿山面临的技术难题,取得了良好的经济效益。Technical status of mining inclined thin ore body is illustrated. To address the problems of high loss and dilution, poor working conditions and low production efficiency 12y use of room and pillar mining method of trench resuing method, with technical innovation in supporting method and rock drilling tools, ＂ long wall, trench cliff, frame shift caving＂ comprehensive mining method is adopted, which successfully resolves the problem of gently inclined thin ore body mining technology and brings out good economic benefits.
