摘要:
金属矿床工业指标的确定直接影响所圈定矿体的形态、采矿方法的选择、采矿损失率和矿石贫化率，间接影响选矿回收率，最终影响开发整个矿床的经济效益。以李坝金矿床为例，介绍了该矿床的边界品位、块段最低工业品位、矿区最低工业品位、最小可采厚度和夹石剔除厚度等工业指标的制定过程，并指出随着企业内部条件和外部环境的变化，工业指标应是一个动态标准，可以修订和优化原有工业指标，应重视和推广应用地质模型的建立，考虑工业指标变化对矿体连续性的影响，采用统计学方法估算资源储量，并根据市场变化实行资源储量和工业指标的动态管理。

Abstract:
The determination of the industrial index metallic deposits directly affects the morphology of delineated ore bodies,selection of mining methods,mining dilution rate and loss rate,indirectly affects recovery rate of ore dressing,and finally affects the economic benefit of developing the entire deposit.This paper takes Liba Gold Deposit for example,introduces the devising process for the industrial indexes such as the cutoff grade in gold deposit,the lowest industrial grade in ore block,the lowest industrial grade in mining area,the minimal mineable thickness and rejecting thickness of dunn bass,and points that the industrial index is a dynamic standard along with the movement of internal conditions and external circumstances in corporations,the original industrial index can be revised and optimized and the geologic model should be emphasized and promoted.Considering the impact of industrial index changes on the continuity of ore bodies,statistical approach should be adopted in estimating reserves,and dynamic management of reserves and industrial index should be implemented according to the changes of market.
