Abstract To meetthedevelopmentrequirementsofdeeporebodiesinamine withyearsofexploitation，thisstudyproposesand compares four development options： a blind belt conveyor decline + auxiliary shaft（hoisting capacity 1.1 Mt/a），a combined shaft （hoisting capacity1.2 Mt/a），a blind combined shaft + auxiliary ramp（hoisting capacity 1.2 Mt/a），and a new main and auxiliary shaft （hoistingcapacity1.8Mt/a）.Acomprehensivetechnical-economiccomparison shows that thenewmainandauxiliaryshaftoption ofersadvantagesinonstructiondificultychedulecontrol，andventilationanddranagesystemesign；althoughitsomprable engineringquantityandcapitalcostarerelativelyigh，itdemostratessignificantlong-teadvantagesinanualcomparablecost andtotalcomparableexpenses，alongwithighproductionmaagementfiency，lowtransportationcosts，andinaliacton existingproduction.Aftercomprehensiveevaluation，thenewmainandauxiliaryshaftoptionisrecommendedasthepreferrd development solution for the deep production substitution project.
