摘　　要：露天金属矿开采常见的方法包括深度开采法、浅部开采法、重力磨砂法和激流磨碎法等,对于不同矿山中金属矿石开采需结合区域地质条件、地形地貌选择合理的方式,使用一种或多种露采方法作出不同产能的金属矿石开采。通过以某地区矿山作为金属矿石开采对象,探讨露采金属矿境界、矿体、断层、围岩和夹石等的空间分布情况,在此基础上制定独立延深开采法、陡帮开采法、诱导冒落开采法相结合的方案,用大型挖掘机、装载机将金属矿石混合物从深层挖出,经由筛分机分离金属矿石、矿砂和土壤,再将金属矿进行分拣、洗涤和干燥即可得到符合要求的金属矿石。露天金属矿协同开采方案能够适应不同地形地质条件的金属矿开采,在降低矿石开采成本的同时,实现金属矿石开采与质量管理的安全性。Common methods for open-pit metal mining include deep mining,shallow mining,gravity sanding,and rapid flow grinding.For metal ore mining in different mines,it is necessary to choose a reasonable method based on regional geological conditions and topography,and use one or more open-pit mining methods to achieve different production capacities.By taking a mine in a certain region as the object of metal ore mining,this study explores the spatial distribution of open-pit metal ore boundaries,ore bodies,faults,surrounding rocks,and interbedded rocks.Based on this,a combination of independent deep mining method,steep slope mining method,and induced caving mining method is developed.Large excavators and loaders are used to excavate the metal ore mixture from deep layers,and the metal ore,sand,and soil are separated by screening machines.The metal ore is then sorted,washed,and dried to obtain the required metal ore.The collaborative mining scheme for open-pit metal mines can adapt to the mining of metal mines with different terrain and geological conditions,while reducing the cost of ore mining and achieving safety in metal ore mining and quality management.
