摘要:
矿产资源边界确定需综合考虑矿产资源的自然属性和经济性，保证矿山开采经济性的同时，使具有经济价值的矿产资源得到合理利用。基于大资源理念引入矿山运营后成本代替全成本，3个步骤完成矿产资源边界的确定，即计算矿山运营后成本、计算矿产资源边际品位、通过资源地质模型确定接近资源边际品位的资源平均品位，接近资源边际品位的资源平均品位最小值就是要确定的资源边界品位。该方法应用于某露天金矿准确圈定了矿产资源最大边界，并能够报告出项目中的资源储量，有助于矿产资源地质师确定合理的矿产资源边界品位，合理圈定和估算资源量。

Abstract:
It is necessary to comprehensively consider the natural property and economy of the mineral resources before the determination of mineral resources boundary,in order to make reasonable use of economically valuable mineral resources and at the same time ensure the economy of mining.Based on the big resource notion,post mining operation cost is introduced to replace overall cost.Mineral resources boundary is determined through 3 steps,that are to calculate the cost after mining operation,to calculate the cut-off grade of mineral resources and to determine the average grade that is close to the cut-off grade of resources using geological model of resources.The minimum of the average grade that is close to the cut-off grade of resources is the one to determine.The method is applied in a open-pit gold mine,and accurately delineates the maximum boundary of mineral resources,can report the mineral reserves in the project,is beneficial for mineral resources geologists to determine reasonable cut-off grade of mineral resources,delineate and estimate mineral reserves in a proper way.
