青南高原砂金矿地质环境恢复治理模式探讨

Discussion on management mode of geological environment recovery of placer mine in southern Qinghai plateau

青海省南部高原砂金矿资源丰富,由于历史上长时期大规模高强度的无序开采,砂金矿区的生态地质环境普遍遭到严重破坏,产生诸多矿山地质环境问题。本文以青南地区开采的砂金矿作为研究对象,系统研究了砂金矿开采产生的主要地质环境问题及其恢复治理概况,在此基础上提出"修复河道+地貌平整+客土回填+植被恢复+后期管护"的恢复治理模式,旨在为类似地区的生态环境修复提供参考。

Southern Qinghai Plateau is rich in placer mine. The geological environment was generally severely damaged in placer gold districts due to disordered large-scale and high-strength mining activities in a long period in history,emerged a lot of mine geological environment problems. This article studied on the placer mines that have been mined in Southern Qinghai Plateau, systematically researched the main geological environment problems and recovery situation. On that basis, it proposed a recovery and management mode of ＂river way repair, landform flattening, soil dressing, vegetation recovery, later period management and protection＂ ,be aimed at provide reference for environment recovery in the similar districts.
