摘　　要：四川省泸沽铁矿始建于1966年,2022年正式更名为四川锦宁矿业有限责任公司大顶山铁矿,采矿权由铁矿山和大顶山两个矿区组成,采矿权面积为2.6683km^(2),生产规模为55万吨/年。大顶山铁矿使用无底柱分段崩落法,地表现已形成较明显的塌陷区,受坡陡谷深的限制,长期边坡排矸,排土场成下游泥石流、滑坡的风险源。为此,本文对冕宁县大顶山铁矿矿山地质环境问题、治理措施及绿色矿山建设进行了探讨,为合理开发利用矿产资源、保护矿山地质环境提供重要参考。Sichuan Lugu Iron Mine was built in 1966 and renamed Dadingshan Iron Mine of Sichuan Jinning Mining Co.,Ltd.in 2022.The mining right consists of two mining areas,namely Iron Mine and Dadingshan.The mining right covers an area of 2.6683km^(2) and the production scale is 550000t/a.Dadingshan Iron Mine uses the pillarless sublevel caving method,and the ground has formed a relatively obvious subsidence area.Limited by the steep slope and deep valley,the waste dump is the risk source of downstream debris flow and landslide.Therefore,this paper discusses the geological environment problems,treatment measures and green mine construction of Dadingshan Iron Mine in Mianning County,providing important reference for rational development and utilization of mineral resources and protection of mine geological environment.
