摘　　要：实现尾砂的综合利用是建设绿色无尾矿山的必要途径。面对技术的进步、政策的变化和市场的不确定性,矿山尾砂综合利用设施及充填系统均应具备一定的适应性。本文结合某矿山实际情况,将该矿选厂所产生的尾砂分为全尾砂、分级细尾砂、分级粗尾砂分别进行研究,通过试验研究及理论计算等方式,对不同尾砂作为充填材料所能消耗的总尾砂量、细尾砂量,运营成本等进行分析。并以此为基础,对充填系统的优化设计及关键设备进行研究,提出了可适应全尾砂充填、分级粗尾砂充填、分级细尾砂充填等多种不同充填工况的最优化充填工艺技术。Comprehensive utilization of tailings is a necessary way to build a green tailings-free mine. Faced with the progress of technology, the policy change and market uncertainty, comprehensive utilization facilities and filling system of tailings should have certain adaptability. According to the actual situation of a mine, the tailings produced by the concentrator of the mine are categorized into unclassified tailings, classified fine tailings and classified coarse tailings. Through experimental research and theoretical calculation, the total tailings amount, fine tailings amount and operating cost consumed by different tailings as filling materials are analyzed. On this basis, the optimized design and key equipment of the filling system are studied, and the optimal filling processes which can adapt to various filling conditions such as unclassified tailings filling, classified coarse tailings filling and classified fine tailings filling are put forward.
