矿产工业指标是圈定矿体、计算储量和评定矿床工业价值必不可少的依据，通过工业指标的制订可以确定可采范围、指导开采工作并合理利用矿产资源。夜长坪钼矿工业指标的制订主要包括边界品位、块段最低工业品位、矿床平均品位等。通过数理统计法、类比法得出夜长坪钼矿边界品位为0．030％，运用经济平衡分析计算得出块段最低工业品位为0．080％，矿床平均品位为0．120％。将经济平衡分析运用到工业指标的制订中能够更加准确地反映出项目未来开发的经济合理性，对其矿床开发的可行性判定起到了重要作用。
Industrial indicators are indispensable parts in the delineation of orebodies ,calculation of reserves and the evaluation of industrial value in deposits .With the determination of industrial indicators ,mining range can be de-cided,mining work is guided and the resources are properly utilized .The indicators in Yechangping Molybdenum Mine mainly include cut-off grade ,minimum industrial grade of ore blocks and average grade of deposits and so on .Mathe-matical statistics and analogy suggest and cut-off grade is 0 .030 %,the economic equilibrium analysis calculates that the minimum grade of ore blocks is 0.080%and the average grade of deposits is 0.120%.Adding economic equilib-rium analysis to the determination contributes to the accuracy when the economic rationalization in future project de -velopment is reflected and is important for the judgment of deposit development feasibility .
