摘　　要：结合峪耳崖金矿缓倾斜矿体顶板破碎极薄矿脉的开采技术条件,设计采用全粒级废石胶结条柱充填连续分条采矿法开采盲9矿体。该采矿方法的使用,降低了充填成本,同时节省了废石运输和提升成本,加强了顶板管理工作,改善了采场作业环境,充分提高了矿石回收率和入选矿石品位,对顶板破碎的缓倾斜矿体极薄矿脉的开采具有一定的借鉴和指导意义。Combining with the conditions of exploitation technology of gently inclined ore body thin veins with broken roof in Yu＇erya Gold Mining,the design uses full grain class continuative section mining with muck cementing pillar to exploit section column filled with waste rock cemented consecutive points of the Blind 9 orebody.The mining method reduced the filling cost,while saved the cost of waste rock transportation and improved the cost,strengthened the roof management,improved the operating environment and fully improved the ore recovery and the grade of selected ore,and it had some reference and guidance on the exploitation of gently inclined ore body thin veins with broken roof.

关 键 词：顶板 极薄矿脉 废石胶结充填 连续回采
