摘要
尾矿具有二次资源和环境污染、安全隐患等危害的双重特性。有效、合理地利用尾矿,实现尾矿的资源化利用尤为必要。我国尾矿综合利用存在着利用率低、资源浪费、政策支持不足和缺乏科技支撑等问题。目前尾矿利用的主要途径有尾矿再选、充填矿山采空区、复垦和综合利用等。推进尾矿综合利用应转变观念、加强政策支持、实施监督管理和加强技术革新。
This paper discusses the importance for effectively and rationally using the tailings;and analyses the problems involved in comprehensive utilization,such as low utilization rate,waste of resources,lack of policy support and scientific support.At present,the main ways for using tailings are: spoil reclaiming,filling mine-out area,reclamation and integrated utilization.Finally,this paper suggests that changing conception,strengthening policy support,exercising supervision and management,and enhancing technical innovation are the main methods for promoting the comprehensive utilization of tailings.
