Abstract：This paper discusses the application value of airborne LiDAR technology in high-precision terrain modeling and mineral reserve estimation in complex mining areas. Centering on the composition of LiDAR system，data acquisitionand processing flow，asetof digital terrain modeling method for complex terrain isestablished.Combined with typical mining area cases，reserve estimation practice is caried out by means of 3D terrain analysis and ore body boundary identification，and the model accuracy is verified.The results show that airborne LiDAR can significantlyimprove theaccuracyand eficiencyof terrainmodelingand stillhasgoodadaptabilityunder complex geomorphic conditions.
