摘　　要：针对湖南宝山矿2号砂页岩深部难采矿体。分析了矿体赋存的地质及开采技术条件．选择上向水平分层进路充填采矿方法开采。回采实践表明：上向水平分层进路充填采矿方法适合于该矿山-190—500m段矿石的安全开采。介绍了采场结构及采矿工艺。The geological and mining conditions of the No.2 deep and difficulty-mined sandy shale ore-body in Hunan Baoshan Mine were analyzed. The horizomal upward sliced drift cut and fill mining method was selected to mine the ore-body.The mining practice showed that this mining method was suitable for safely mining the sandy shale ore-body from -190 m to -500 m in the mine.The stope structure and mining technology of the mining method are introduced in this paper.

关 键 词：复杂难采矿体 上向水平分层进路充填采矿法 采场结构 采矿工艺
