摘　　要：为减少矿产开采活动对矿山地质环境破坏的影响,分析了研究区的矿山地形地貌及地层岩性特征,对吴营铁矿地质环境影响现状和矿山地质环境影响进行了评估。现状评估结果表明,露天采坑发生崩塌地质灾害的可能性小,危险性小;地下采空区发生采空塌陷、地裂缝地质灾害可能性小、危险性小;根据矿山地质环境预测评估结果,将评估区分为3个区:矿山地质环境影响程度严重区、较严重区及较轻区。矿业活动未直接影响区域面积3112120 m^(2),占评估区总面积的96.31%,防治难度较小。总结了矿山地质环境保护与恢复治理技术,主要包括露天采坑防治技术、岩石移动治理技术、工业场地治理技术、矿区道路治理技术、排土场治理技术、硐口治理技术、废渣堆治理技术等。研究为矿区及周围生态环境的防治提供了参考依据。In order to reduce the damage to the geological environment of the mine caused by the mining activities,this paper analyzed the topography and lithology of the mine in the study area,and evaluated the current situation of the geological environment of the Wuying Iron Mine and the prediction of the geological environment of the mine.The possibility and risk of collapse geological disasters are small;underground goaf have low probability and low risk of gob collapse and ground fissures geological disasters.According to the prediction and evaluation results of mine geological environment,the evaluation is divided into three areas:the area with serious impact on mine geological environment,the area with more serious impact and the area with less impact.The area not directly affected by mining activities is 3112120 m^(2),accounting for 96.31%of the total area of the assessment area.It is less difficult to prevent and control.This paper summarized the mine geological environment protection and restoration treatment technology,mainly including open pit prevention and control technology,rock movement treatment technology,industrial site treatment technology,mining area road treatment technology,waste dump treatment technology,tunnel mouth treatment technology,waste dump treatment technology,etc.The study provides a reference basis for the prevention and control of mining area and surrounding ecological environment.
