摘　　要：针对顶板薄层岩体极破碎缓倾斜薄矿体的开采方法,目前没有查询到对其开采采用新技术、新工艺的相关报道。其回采仍采用混采工艺,因混采而造成的废石混入率居高不下,直接影响了企业的经济效益和社会效益。对该种类型的矿体开展回采工艺的试验研究,对于降低废石混入率,提高企业经济效益及推进绿色矿山建设具有重要的现实意义。There are currently no reports on the use of new technologies or processes for the mining of extremely fractured and gently inclined thin ore bodies in thin roof rock masses.The mining still adopts mixed mining technology,and the high rate of waste rock mixing caused by mixed mining directly affects the economic and social benefits of the enterprise.The experimental research on the mining process of this type of ore body has important practical significance for reducing the waste rock mixing rate,improving the economic benefits of enterprises,and promoting the construction of green mines.

关 键 词：缓倾斜薄矿体 顶板薄层极破碎 分层爆破 削壁充填
