摘要： A mine digital model construction method based on a three-dimensional point cloud database is disclosed. Mine data resources are collected, valid coordinate point position information is extracted according to point cloud data extraction standards, and a mine three-dimensional point cloud database is established; a model of rock strata boundary surfaces, mining areas, and tunnels is constructed, a surface three-dimensional geological model is constructed, and a mine three-dimensional geological model is further constructed; and division into grids is performed to obtain a mine extraction inversion digital model. According to the method, a mine three-dimensional point cloud database can be obtained, and various identified rock strata topographies, positions of mining areas and tunnels, fault morphologies, and surface morphologies can be restored; mine extraction inversion digital models having different precisions can be constructed, a foundation is laid for crustal stress field inversion, and a reliable basis is provided for mine disaster prevention and control.
