三维地质模型驱动的露天煤矿岩体爆破优化设计
Optimization design of rock mass blasting in open-pit coal mines driven by 3D geological modeling
摘要
Abstract
This article proposes a 3D geological model-based blasting design optimization method to improve the efficiency and safety in open-pit coal mining of soft-hard interlayer rock masses.By lithological geological logging and spatial interpolation technology,the article creates a precise 3D lithological mode,and realizes accurate characterization of rock mass structure.On the basis of it,aiming at differences in mechanical properties of sandstone,mudstone,and cemented rock,the article designs differentiated hole network parameters and layered charging schemes.Field results show that the method effectively improves homogeneity of blasting energy distribution,reduces blasting vibrations and rock mass disturbances,offering a new approach to blasting design in complex geological conditions.关键词
