废弃铝土矿主要地质环境问题与修复治理方案择选

针对北冶镇裴岭村后岭废弃铝土矿主要地质环境问题，认为其地质灾害隐患主要由原采矿活动遗留的高陡边坡、采坑、不稳定边坡以及渣堆造成，并且导致含水层破坏、水土流失、地形地貌景观破坏等。提出了针对性的防治工程比选方案，对方案1和方案2进行比选可知，2个方案均能达到此次矿上环境治理的目的，且预计都能取得良好的成果。但相较而言，方案1在能达到同样目的的情况下，更经济实惠。采取挖填方工程、覆土及平整工程、田埂工程、土壤改良工程、绿化工程、养护工程等工程手段恢复研究区内土地功能，改善地形地貌环境、恢复植被，达到改善研究区整体生态环境条件的目的。

Main geological environmental problems of abandoned bauxite and selection of remediation and treatment schemes

Aiming at the main geological environmental problems of Houling abandoned bauxite mine in Peiling Village，Beiye Town，the hidden dangers of geological disasters are mainly caused by the high and steep slopes，mining pits，unstable slopes and slag piles left by the original mining activities，and the damage to the aquifers，soil erosion，topography and landscape damage，etc.The comparison and selection scheme of targeted prevention and control projects was proposed.The comparison of scheme 1 and scheme 2 shows that both schemes can achieve the purpose of this mine environmental governance，and are expected to achieve good results.However，in comparison，scheme 1 is more economical when it can achieve the same purpose.Take excavation and filling engineering，soil covering and leveling engineering，ridge engineering，soil improvement engineering，greening engineering，maintenance engineering and other engineering methods to restore the land function in the study area，improve the topography and landform environment，and restore vegetation，so as to achieve and improve the overall ecological environment of the study area.the purpose of the condition.
