摘　　要：以辰州矿业公司沃溪矿区为工程背景,根据矿体开采技术条件,初选了4种可适用于缓倾斜薄矿体的采矿方法,并优选出竖分条光面一次扩界嗣后充填采矿法为最佳方案。详细介绍了竖分条光面一次扩界嗣后充填采矿法回采工艺及应用取得的主要技术经济指标。应用实践体现了该采矿法开采缓倾斜薄矿体的优越性,可为同类矿山的开采提供借鉴。The paper takes Woxi Mining District of Chenzhou Mining Co., Ltd. as the engineering background, and according to the technical conditions of orebody extraction, reaches 4 mining methods applicable to moderately inclined thin orebodies among which is the optimal plan of vertical slicing subsequent filling mining method with once boundary extension of smooth face. The paper elaborates the main technical indexes its application achieved. The application practice proves the advantages the method has in extracting moderately inclined thin orebodies and can provide guid- ance for similar mines.
