Abstract
To facilitate the application of 3D geological models in underground mining operations,this study proposes a three-dimensional visualization and dynamic classification system for rock mass quality in underground mines.The investigation combines digital close-range photogrammetry with traditional manual measurements,using RMR values as the core evaluation metric.Spatial interpolation employs the inverse distance power law method(power exponent set to 2)to construct block models(with 10 m×10 m×10 m cells)containing(x,y,z,RMR)data sets.Subsequent cross-sectional analysis through 3D modeling reveals dynamic distribution patterns across various levels and key zones.This research conducted digital close-range photogrammetric surveys and manual measurements within the+0 to+90m horizontal range of the West Area at Makeng Iron Mine,establishing a geological database and recommended block models for dynamic rock mass classification.Results indicate that Grade Ⅱ rocks account for 38.3％,Grade Ⅲ for 61.6％,and Grade Ⅳ for 0.01％in this area,demonstrating generally favorable rock mass quality.These findings provide decision-making support for underground mining operations.关键词
