摘　　要：针对陇东黄土高原生态脆弱区的矿山地质生态环境,以蒲河流域A废弃平硐采砂矿山为例,在综合考虑该矿区环境现状和影响因素及生态修复过程中存在的难题基础上,进行矿山地质环境影响评价及修复技术研究。结果表明:人为不合理矿产开发活动破坏了地质环境条件,在降雨、地震等影响下矿区容易再次发生滑坡、崩塌等地质灾害;破坏地形地貌景观面积13.93 m^(2),破坏地表草皮和上层土层剥离面积13.93 m^(2),压占土地面积1.11 hm^(2),影响区范围510.9 hm^(2);矿区通过地形地貌重塑、地质灾害隐患消除、植被恢复和土地复垦等综合治理措施,可有效恢复矿区内地质环境和生态环境条件。In response to the geological and ecological environment of mines in the ecologically fragile area of the Loess Plateau in Longdong,taking abandoned adit sand mining mine A in the Puhe River Basin as an example,based on comprehensive consideration of the current environmental status and influencing factors of the mining area,as well as the problems existing in the ecological restoration process,a study was conducted on the impact assessment and restoration measures of the geological environment of mines.The results indicate that human unreasonable mineral development activities have damaged the geological environment conditions,and the mining area is prone to geological disasters such as landslides and collapses under the influence of rainfall,earthquakes,etc;the area of terrain and landscape destruction is 13.93 m^(2),the area of surface grass and topsoil stripping is 13.93 m^(2),the land occupation area is 1.11 hm^(2),and the affected area is 510.9 hm^(2);the mining area can effectively restore the geological and ecological environment conditions within the mining area through comprehensive management measures such as terrain and landform reshaping,elimination of geological hazards,vegetation restoration and land reclamation.
