庆阳市马半坡砂矿地质环境特征与恢复治理研究

Study on geological environment characteristics and restorationof Mabanpo placer in Qingyang City

庆阳市马半坡砂矿矿区位于鄂尔多斯盆地庆阳单斜构造东南部,地貌类型属陇东黄土高原沟壑区。地质环境调查表明,矿山地质环境问题主要为无序的采矿活动形成的地质灾害、地形地貌景观破坏和土地资源破坏3种。地质灾害为X1、X2两处不稳定斜坡,地形地貌景观破坏主要为采坑和窑洞,土地资源破坏主要为采坑挖损和渣堆压占。采取有效的工程手段治理矿区生态环境,改善了当地自然环境。

Mabanpo placer located in the southeast of Qingyang monocline,Ordos Basin,and in the gully region of Longdong Loess Plateau.Through the investigation of geological environment in the mining area,this paper found out that the geological environmental problems of the mine are due to disordered mining activities,destruction of landform and geomorphic landscape,and destruction of land resources.The geological disasters are X 1 and X 2 unstable slopes.The main damage of land resources is the excavation loss and the slag muck occupation.Taking effective engineering measures to control the ecological environment of mining area can effectively improve the local natural environment.
