摘　　要：基于淮北陈庄铁矿现场调查、水土采样测试、测量等工作,从地质灾害发育情况、地形地貌景观破坏、含水层破坏、土地资源压占损毁、水土污染等方面,分析矿山开采历史及预测矿业活动引起的采空塌陷对生态环境的影响。针对矿山采空塌陷问题,采用分段空场嗣后干式充填采矿法,尽量减少采空塌陷的形成,矿山闭坑后废弃井筒密闭填充,拆除相关建筑物,覆土整平、土地复垦、地质环境治理保护等手段以达到减小对生态环境的破坏。Based on the field investigation,water and soil sampling test,and measurement of the Chenzhuang iron mine in Huaibei,the mining history analysis and prediction of the influence of mining subsidence caused by mining activities on ecological environment wereconducted from the aspects of geological hazard development,topography and landscape damage,aquifer damage,and water and soil pollution.The sublevel open stoping subsequent dry filling mining method wasused to minimize the formation of mining subsidence.In addition,after the mine was closed,closed filling of abandoned shafts,demolition of related buildings,leveling of soil cover,land reclamation,and geological environment protection measures were adopted to reduce damage to the ecological environment.
