摘　　要：针对湘西金矿缓倾斜薄矿脉开采存在的突出问题,本课题从提高机械化作业水平和改革回采工艺着手,采用微型电动铲运机出矿与辅助充填,应用定向抛掷爆破削壁充填技术,提高了采场生产能力,减轻劳动强度,较好地解决了充填接顶问题,试验获得成功。In view of the remarkable problems existing in mining the flat-dipping thin vein in Xiangxi Gold Mine, we try to improve mechanized operation and innovate mining technology by using miniature electric-powered LHD's for ore removal and filling assistance.The technology of resuing-and-filling by oriented pin-point blasting has also been applied. Therefore, stope productivity was raised, labour force was lowered, and problems with closed roof filling were solved satisfactorily. This experiment proved to be a success.
