Mine Geological Environment Quality Assessment Technology Based on Airborne LiDAR

Abstract

It is critical to master the geological environment of the mining area for resource development and subsequent restoration. Based on airborne LiDAR point cloud data, this study took an open-pit mining area in Ma'anshan City as the study area. Firstly, selected the evaluation indexes and calculated the weights of each index. Secondly, Construct the mine geological environment evaluation system and determine the classification grades. Finally, A comprehensive evaluation model was established to evaluate the quality of the geological environment in the study area. The results show that there are only two grades of “good” and “poor” geological quality in the study area, and the proportion of the area is 48.31 % and 51.69% respectively.
