小秦岭金矿区地质灾害分析及治理

Geological hazard analysis and remediation in Xiaoqinling Gold District

随着小秦岭金矿区坑口逐渐关闭,开展矿山地质灾害调查和治理工作势在必行。基于矿区地质环境,分析了区域内的地质灾害类型,并采取废渣清运,修筑防护堤、拦渣坝、挡渣墙,沟道整治与道路修复、植被恢复等针对性措施进行治理。小秦岭金矿区修建挡渣墙2.88万m^(3),固定矿渣2002万t,清运矿渣584万t,平整渣坡143.5万m^(2),修建渣坡排水渠21.2 km,清理疏通河道15.5 km,栽植各类苗木80.7万株,撒播草种14.6 t,环境效益显著,可为类似地质灾害治理提供借鉴和参考。

As the shafts in Xiaoqinling Gold District gradually close,it has become imperative to conduct geological hazard investigations and implement remediation measures.Based on the geological environment of the mining area,this study analyzes the types of geological hazards in the region and implements targeted remediation measures,such as waste residue cleaning and transportation,construction of protective dikes,debris retention dams,debris retention walls,trench rehabilitation,road repairs,and vegetation restoration.In Xiaoqinling Gold District,28800 m^(3)of debris retention walls were constructed,stabilizing 20.02 million t of ore residue,cleaning and transporting 5.84 million t of residue,leveling 1.435 million m^(2)of residue slopes,constructing 21.2 km of drainage channels along residue slopes,clearing and dredging 15.5 km of river channels,planting 807000 saplings,and sowing 14.6 t of grass seeds.The environmental benefits have been significant,providing valuable insights and references for similar geological hazard remediation efforts.
