摘要
东昆仑红旗沟锰矿位于柴达木盆地东南缘,具有较好的锰成矿环境,矿区含矿岩性主要为硅质大理岩。矿业开发引发了各类地质环境问题,经过评估,不稳定斜坡7处,危险性中等;易发生崩塌地质灾害1处,危害程度中等,危险性中等;发育泥石流沟1处,危害程度大,危险性大。通过矿山地质环境治理,恢复地形地貌景观,重建破坏的生态功能,促进生态系统的良性循环,并产生较好的社会效益和经济效益。
Hongqigou manganese deposit in East Kunlun is located in the southeast margin of Qaidam basin with a good manganese metallogenic environment.The ore-bearing lithology of the deposit is mainly siliceous marble.Mining development has caused various geological environmental problems.According to the assessment,there are 7 unstable slopes in moderate risk,of which we have found the geological hazard prone to collapse with moderate hazard and risk.The debris flow gully is developed with great hazard and danger.Through the treatment of mine geological environment,the landform and landscape will be restored.The damaged ecological function will be reconstructed and the virtuous cycle of the ecosystem will be promoted.In doing so,the good social and economic benefits will be generated.
