To carry out deep prospecting for the Xiagalaiaoyihe lead-zinc polymetallic deposit,three-dimensional geological modeling of the deep strata and ore bodies was conducted using Micromine software,based on geological and ore geological data of the mining area,and achieved a three-dimensional visualization and transparency of the deep geological bodies.The cubic prediction model and prospecting information quantity method were used to statistically analyze multi-source geological data in the mining area.Finally,3 lead-zinc mineralization target areas and 4 magnetite mineralization target areas were delineated within the mining area,providing reference and basis for future prospect-ing work.
