摘  要:阿尔巴尼亚Perlat铜矿是典型的缓倾斜薄至中厚矿体,矿体大部分位于地表河流正下方,连续性较差,可分为上下多层矿体,且厚度较薄,延伸有限,规模不大。为保证开采作业安全,提高矿石回收利用率,提出了上向进路充填采矿法。该方法不仅能有效控制地压活动的危害,降低采场突水风险;同时将矿石的贫化率控制在6%,损失率控制在8%以内,最大限度地回收铜资源;采用胶结与非胶结相结合的充填工艺,降低了充填成本,充分利用尾矿作为充填材料,减少了尾矿库的占地,具有良好的经济效益和社会效益。The orebody of Perlat Copper Mine in Albania is a typical gently inclined orebody with the thickness from thin to medium thick,which is mostly located under the river.It has the characteristics of poor continuity,multi-layered deposits,thin thickness,limited extension and small scale.In order to ensure the safety of mining operations and improve ore recovery efficiency,upward drift stoping with backfill was proposed.This method not only effectively controlled the hazards of ground pressure to reduce the risk of water inrush in stope,but also commanded the dilution rate of ore within 6% and the loss rate within 8%to recycle copper resources as far as possible.The utilization of filling process combining cementing and uncementing reduced the filling cost,as well as the area of tailings reservoir by taking full advantage of tailings as filling material,which had good economic and social benefits.
