Abstract：A certain lead-zinc ore is located in Huayuan county，Hunan province，with a mining area of 22.90km2 ，and the continuityoftheorebodyvariesgreatlyandthegradeandthicknesschangesignificantly.Thecontinuityradedistribution andthickness variationcharacteristicsoftheorebodyaresystematicallyanalyzed，threesetsof industrialindicatorshemes aredesigned，andtheschemesarecomparedbasedonorebodydelineation，resourcecalculationandeconomicevaluation todeterminetheoptimal industrial indicators.Theresearch results indicatethatcomparedto SchemeIand Scheme Il ， Scheme I hasthe most advantages，with areasonable internal structure oftheore body，ensuring continuityand controlling ore quality.The amount of Zn metal in the industrial ore body of Scheme is 2.355 8 million tons，accounting for 83.21% Asthe optimal industrial indicator，the Zn boundary grade is 0.5% ，the minimum industrial grade of Zn is 1.2% ，the minimum mineable thickness is 1.8 m，the removal thickness of interbedded stones is 4.0m ，and the associated Pb grade is 0.10% .Scheme I can avoid excessive mixing of low-grade ore and fragmentation of the ore body，achieving the optimal balance between ensuring thecontinuityoftheore body，controling orequality，and improving economic benefits.
