摘要
针对海岛环境下露天废弃矿山生态修复与地质灾害防治需求,以浙江省舟山某废弃矿山为研究对象,通过野外调查、地质资料分析与数值模拟,系统研究了矿区工程地质条件及边坡稳定性,提出了综合治理方案。基于综合评价,提出“削坡整形+安全平台”“截排水系统优化”“高性能生态基材喷播”三位一体治理策略:削坡整形清除危岩体并重塑坡形;分级布设截水沟与透水排水沟,控制地表径流与孔隙水压力;采用植生袋围堰、挂网喷播及乔灌草组合复绿技术,兼顾稳定性与生态功能。研究结果可为海岛露天废弃矿山综合治理提供技术参考,强调以自然恢复为基础,结合人工干预实现生态修复与灾害防治协同,助力区域可持续发展。
To address the ecological restoration and geological hazard prevention needs of abandoned openpit mines in island environments,this study focuses on a case of an abandoned mine in Zhoushan,Zhejiang Province.Through field investigations,geological data analysis,and numerical simulations,we systematically examined the engineering geological conditions and slope stability of the mining area,proposing an integrated remediation solution.Based on comprehensive evaluation,a tripartite management strategy was established as by slope cutting and reshaping safety platforms to remove hazardous rock masses and reconstruct slope geometry,optimized drainage system featuring graded interception ditches and permeable drains to control surface runoff and pore water pressure,high-performance ecological substrate sprayin employing vegetation bag cofferdams,mesh-hanging spraying,and composite revegetation techniques combining trees,shrubs,and grasses to balance stability and ecological functions.The findings provide technical references for comprehensive management of island abandoned mines,emphasizing nature-based restoration complemented by artificial interventions to synergize ecological rehabilitation with hazard mitigation,thereby promoting regional sustainable development.
